  The magnetism and work function of pure Ni() and Ni-Cu slab alloys were investigated using first-principles methods based on density functional theory. The calculated results reveal that both magnetic moments and work functions of the alloys depend strongly on the surface orientation, but hardly on the distribution of doped Cu atoms for a given surface orientation. Abstract. Magnetic micro- and nanogranular materials prepared by different methods have been used widely in studies of magnetooptical response. However, among them there seems to be nothing about magnetic nanogranular thin films prepared by a cosputtering technique for both metals and insulators till now. This paper presented and discussed preparation, structural characteristics, and magnetic.

  Properties. Individual pure metals may possess useful properties such as good electrical conductivity, high strength, and hardness, or heat and corrosion resistance. Commercial metal alloys attempt to combine these beneficial properties in order to create metals more useful for particular applications than any of their component elements. In the present work, the dealloying of Al–Au-based precursors and formation of nanoporous Au-based alloys have been investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM) and energy dispersive X-ray (EDX) results show that the addition of Ni and/or Co has no influence on phase.

  Recently, amorphous magnetic semiconductors as a new family of magnetic semiconductors have been developed by oxidizing ferromagnetic amorphous metals/alloys. Intriguingly, tuning the relative atomic ratios of Co and Fe in a Co-Fe-Ta-B-O system leads to the formation of an intrinsic magnetic semiconductor. The Alloys The Ni-Resist cast irons are a family of alloys with sufficient nickel to produce an austenitic structure which has unique and superior properties. The family is divided into two groups. These are the standard or flake graphite alloys and the ductile or spheroidal graphite alloys. Except for the copper containing ones, the groups have.

Non-destructive magnetic point control of the martensite content in low-magnetic austenitic alloys is a new method for detection of the local sites with internal stresses. The ternary alloy Co–Fe–Ni demonstrates good soft magnetic properties which can be applicable to design of some devices such as write head core materials in hard disk.

In this article, the more details of alloying effects on both structural and magnetic properties of Fe 50 Co 30 Ni 20 system have been by: This book presents the features of the ternary phase diagrams Ni-Al-X (X = {Co, Fe, Nb, Ti, Cr}), effects of the alloying on the long-range order and mechanical properties of the Ni3Al-based alloys.

The experimental results on these compounds must be related to the properties of the perfectly ordered Ni3Al compound.

A discussion of this relationship and the resulting information concern- 2 N. Buis et al. /Magnetic properties of Ni3Al under high pressures ing the properties of perfect Ni3A1 is the main subject of this paper. Superalloys form a class of the structural materials for high-temperature applications.

Nickel superalloys are extensively used in the high-temperature components of gas turbines due to their excellent creep, fatigue, and corrosion resistance at elevated temperatures.

These materials are considered paramagnetic in the range of working temperatures. This book presents the features of the. The properties of both the ordered-7' and the disordered-7 phases as well as the thermodynamics and kinetics of the 7 ~ transformation at Tcr can be studied by various techniques [3] when Tcr is below the melting temperature T~ of the alloy.

The ingots were cast into a copper mold to prepare bulk samples. Magnetic measurements in the temperature range from 5 to K were measured using a PPMS EverCool-II magnetometer in the maximum magnetizing field up to 90 kOe. Abstract: We have systematically investigated the microstructural effects including grain size, precipitation, and structural order parameter on the high temperature magnetic and mechanical properties of FeCo-based commercial alloys.

At high temperatures the equilibrium nonmagnetic precipitates significantly deteriorate the soft magnetic properties. Poor mechanical properties are.

The perturbation of the magnetic moments by atom substitution is mainly dominated by the Mn environment. This study is expected to provide information on composition-related structure and magnetic properties of Ni–Mn–Ga alloys that could not be obtained by experiments.

Glassy Metals: Magnetic and Structural Properties edited by R Hasegawa ( Boca Raton, Florida: CRC Press). Most of these books contain chapters on magnetic properties, but separate reviews on magnetic properties have been written by Graham and Egami () and Luborsky (a).

A large number of papers in this field have. Abstract: This study presents the structural and magnetic properties of melt-spun HfCo 7,HfCo 7-x Fe x ( ≤ × ≤ 1) and HfCo 7 Si x ( ≤ × ≤) alloys. Appreciable permanent-magnet properties with a magnetocrystalline anisotropy of about Mergs/cm 3, a magnetic polarization J s ≈ kG, and coercivities H c = kOe were obtained by varying the composition.

The paper studies the influence of magnetic field on magnetic and mechanical properties of Cu–Mn–Al alloy under annealing. The comparative analysis of the magnetic field orientation impact on solid solution decomposition processes in a fixed annealing procedure is held using the methods of low-field magnetic susceptibility, specific magnetization, and microhardness test.

The magnetic properties of Fe‐Si‐B‐M (M: additives) alloys prepared by annealing amorphous alloys made by the single roller method over their crystallization temperature have been investigated for development of new Fe‐based soft magnetic alloys.

Excellent soft magnetic properties were obtained by adding the two elements Cu and Nb to Fe‐Si‐B alloys. Magnetic alloys. Magnetic alloys are alloys engineered to have special magnetic properties.

Permalloy. Permalloy is the term for a nickel iron magnetic cally, it refers to an alloy with about 20% iron and 80% nickel loy has a high magnetic permeability, low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance.

In Fig. 1, the crystal structure of NiAs-type MnBi and alloys based on this structural template with composition MnBi-Co and MnBi-Co-Fe are shown. As shown in Figs. 1(b) and 1(c), there is particular interest in investigating cases when transition metal atoms occupy the interstitial sites of the NiAs MnBi structure.

The contribution of the structural disorder to the magnetic properties is found directly by comparing the results for the amorphous Fe 80 P 13 C 7 and Co 75 Si 15 B 10 with those for the corresponding single‐phase crystalline bcc Fe‐P‐C and hcp Co‐Si‐B, which were obtained by careful thermal treatments.

The interpretation of the magnetic properties of pure transition metals at finite temperature is still a matter for debate1 so little will be said about alloys at finite T. However, considerable progress has been made in the calculation of spinwave energies and these collective elementary excitations dominate the low-temperature properties in.

Most metals and alloys crystallize in one of three very common structures: body-centered cubic (bcc), hexagonal close packed (hcp), or cubic close packed (ccp, also called face centered cubic, fcc).

In all three structures the coordination number of the metal atoms (i.e., the number of equidistant nearest neighbors) is rather high: 8 for bcc.In this review, we highlight the achievements of atomically precise alloy nanoclusters, and summarize the alloying principles and fundamentals, including the synthetic methods, site-preferences for different heteroatoms in the templates, and alloying-induced structure and property changes.
