Electrical resistivity of Heusler alloys

Solid State Communications, 1982
Abstract The electrical resistivity of eight different Heusler alloys is discussed in terms of electron phonon and spin-disorder scattering. The systematics common to the alloys can be explained in the intermediate to high temperature range while the low temperature range still presents interpretation difficulties.

Fe-based semiconducting Heusler alloys

Semiconductors, 2017
A brief overview of the current state of research on Fe-based semiconducting Heusler alloys is given. The most significant achievement in this area is the increase of thermoelectric figure of merit to ZT > 1 in the p-type Fe(V,Nb)Sb-based compounds.

Heusler alloy/semiconductor hybrid structures

Current Opinion in Solid State and Materials Science, 2006
Abstract Heusler alloys are theoretically predicted to become half-metals at room temperature (RT). The advantages of using these alloys are good lattice matching with III–V semiconductors, high Curie temperature above RT and intermetallic controllability for spin density of states at the Fermi level.

Clustering in Heusler Alloys

2009
The effect of disordering, particularly Cr clustering on the magnetic properties in bulk and nanosized Heusler alloy Fe2CrAl has been studied using a combination of X-ray diffraction, 57Fe Mossbauer spectroscopy, and DC magnetization. The structural order/disorder has been confirmed using Mossbauer spectroscopy, and the observed bulk magnetic ...

Spin dynamics in Heusler alloys

Journal of Magnetism and Magnetic Materials, 1983
Abstract The transverse dynamical spin susceptibility of ferromagnetic Heusler alloys X 2 MnY(X = Ni, Cu, Pd, Y = Al, Sn) is evaluated within RPA with the use of the energy values and the wave functions determined by the T.B.-OPW method. The magnetic interactions in these alloys are investigated through the results and compared with experimental ...

Magnetization of Quaternary Heusler Alloy CoFeCrAl

IEEE Transactions on Magnetics, 2022
We report the magnetovolume effect of quaternary Heusler alloy CoFeCrAl as a potential candidate of spin gapless semiconductor. The crystal structure of CoFeCrAl was confirmed as the single phase of the ordered LiMgPdSn-type structure. From magnetization measurements at ambient pressure, the Curie temperature TC and the spontaneous magnetization Ms ...

Ferromagnetic Shape Memory Heusler Alloys

Solid State Phenomena, 2012
Although Heusler alloys have been known for more than a century, but since the last decade there has been a quantum jump in research in this area. Heusler alloys show remarkable properties, such as ferromagnetic shape memory effect, magnetocaloric effect, half metallicity, and most recently it has been shown that it can be used for direct conversion of

Magnetic Order in Heusler Alloys

1994
The magnetic properties of the ternary Heusler alloys are modeled by a Heisenberg Hamiltonian that includes first, second and third-nearest-neighbor interactions. The magnetic ground state structures at zero magnetic field and their range of stability with regard to the interaction parameters are obtained using the method of linear inequalities.

XII.—Heusler's Magnetic Alloy

Proceedings of the Royal Society of Edinburgh, 1907
Since the discovery by Heusler in 1903 of a magnetic alloy of copper, manganese, and aluminium, considerable interest has been aroused by the peculiarities of its properties and the difficulty of their explanation. In the summer of 1905 a preliminary investigation of a sample of the alloy was made in the Physical Laboratory of Glasgow University, and ...

Magnetic moments in heusler alloys

Journal of Magnetism and Magnetic Materials, 1976
Abstract The Heusler alloys are a series of local moment ferromagnets of composition X 2 Mn Y , with a magnetization of ∼4 mu B per Mn atom. Magnetic measurements on the alloy series Ni 2 Mn x T 1− x Sn, where T is Ti, V or Cr, indicate that the T site moment changes from −mu B (for Ti), through zero (for V), to + mu B (for CR).
