Ferromagnetic half-metallicity in half-Heusler AuMnSn:Te Alloy

Materials Research Express, 2020
Identifying a strategy for beneficial band-engineering is vital for the optimization of spintronic materials. In this study, we demonstrate the beneficial effects of electron doping on ferromagnetic (FM) half-Heusler AuMnSn _1− _x Te _x (0 ≤  x  ≤ 1) using state-of-the-art first-principles methods.

Effect of spin-orbit coupling in noncentrosymmetric half-Heusler alloys

Physical Review B, 2023
Spin-orbit coupled electronic structure of two representative non-polar half-Heusler alloys, namely 18 electron compound CoZrBi and 8 electron compound SiLiIn have been studied in details. An excursion through the Brillouin zone of these alloys from one high symmetry point to the other revealed rich local symmetry of the associated wave vectors ...

Lattice Dynamics and thermodynamic Responses of XNbSn Half-Heusler Semiconductors: A First-Principles Approach

Journal of Nigerian Society of Physical Sciences, 2021
In this work, we have evaluated how CoNbSn, IrNbSn, and RhNbSn half Heusler alloys respond to temperature change and the accompanying lattice vibrations as a cubic crystal. There are reports in the literature for CoNbSn with which we compared our result;

Intrinsic point defects in thermoelectric half-Heusler alloys [PDF]

Scripta Materialia, 2014
The single-phase half-Heusler microstructure of ZrNiSn, (Zr0.5, Hf0.5)NiSn and Zr(Ni, Co0.2)Sn alloys was found to contain a high density of Heusler lattice bands 2–7 nm wide. These nanoscale Heusler lattice bands originated from clustering of Ni and/or Co antisites via occupation of structural vacancies by excess Ni or (Ni+Co) concentrations.

Electronic, magnetic and galvanomagnetic properties of Co-based Heusler alloys: Possible states of a half-metallic ferromagnet and spin gapless semiconductor

AIP Advances, 2021
Parameters of the energy gap and, consequently, electronic, magnetic and galvanomagnetic properties in different X2YZ Heusler alloys can vary quite strongly.

Generalized Slater-Pauling rule for the inverse Heusler compounds [PDF]

, 2012
We present extensive first-principles calculations on the inverse full-Heusler compounds having the chemical formula X$_2$YZ where (X = Sc, Ti, V, Cr or Mn), (Z = Al, Si or As) and the Y ranges from Ti to Zn.

A half-metallic half-Heusler alloy having the largest atomic-like magnetic moment at optimized lattice constant

AIP Advances, 2016
For half-Heusler alloys, the general formula is XYZ, where X can be a transition or alkali metal element, Y is another transition metal element, typically Mn or Cr, and Z is a group IV element or a pnicitide.
