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).

Heusler-alloy films for spintronic devices

Applied Physics A, 2013
The next generation of magnetic memories requires an ideal spin-polarised electron source, achievable by using a half-metallic Heusler-alloy film. For Heusler-alloy film implementation, it is critical to realise both large volumes of coherent magnetisation reversal and high interfacial atomic ordering.

The silver-based heusler alloys

Philosophical Magazine, 1959
Abstract The structures of some fifty alloys of silver, manganese, and aluminium have been studied with a view to explaining the magnetic properties of these alloys. Approximate equilibrium diagrams were made at 400°c and 660°c, and the alloys were also examined after quenching from the latter temperature.

A Band Model for Heusler Alloys

MAGNETISM AND MAGNETIC MATERIALS — 1973: Nineteenth Annual Conference, 1974
The band structure of Heusler alloys is simulated by a free electron conduction band which hybridizes with a flat band due to the “magnetic” ions (e.g. Mn in Cu2 Mn Al), The magnetic properties are due to a Coulomb repulsion between electrons of opposite spin in the flat band.

Theoretical study of Ni2MnGa Heusler alloy

AIP Conference Proceedings, 2012
The structure determination of Ferromagnetic Shape Memory Alloy Ni2MnGa is a major challenge. This paper reports the investigation of the properties of Ni2MnGa Heusler alloy from the theoretical point of view using density-functional calculations through Gaussian.
