“…Heusler compounds are intermetallics with intriguing magnetic properties 1–3 . The term derives from the name of the German mining engineer and chemist, Friedrich Heusler, who studied such compounds in 1903 4 . A typical compound contains two parts copper, one part manganese, and one part aluminum, i.e., Cu 2 MnAl.…”

Rapidly quenched ternary Ni-Mn-T (T = In, Sn) alloys exhibit features associated with magnetic skyrmions, so that XRD, TEM, EDS, SAED and HREM investigations were carried out for structural characterization on the two alloy systems. In this paper, we report a new type of Mn-rich Heusler compound with a cubic unit cell, a = 0.9150 nm in Ni-Mn-In and a = 0.9051 nm in Ni-Mn-Sn, which coexist with a Ni-rich full-Heusler compound with defects, a = 0.6094 nm in Ni-Mn-In and a = 0.6034 nm in Ni-Mn-Sn. A further analysis of the experimental results reveals a close structural relationship between these two compounds.

“…Heusler alloys are named for the German mining engineer and chemist Friedrich Heusler, who investigated Cu-Mn-Al alloys around the year 1900. Heusler compounds are ternary intermetallic compounds, which have been known since 1903 [15]. These alloys were interesting because some of them were ferromagnetic, even though their constituent atoms were non-ferromagnetic as elements.…”

First-principles calculations were used to investigate several inverse Ti2CoSi-based compounds. Our results indicate that Ti2CoSi could transform from a spin-gapless semiconductor to a half metal if a quarter of the Co atoms are replaced by Ti. Ti2.25Co0.75Si would keep stable half-metallic properties in a large range of lattice parameter under the effect of hydrostatic strain, and would become a gapless half metal under the effect of tetragonal distortion. Furthermore, we substituted B, Al, Ga, P, As, and Sb for Si in the Ti2.25Co0.75Si compound. Our results demonstrate that Ti2.25Co0.75Si0.5B0.5, Ti2.25Co0.75Si0.5Al0.5, and Ti2.25Co0.75Si0.5Ga0.5 are half-metallic ferromagnetic materials, and Ti2.25Co0.75Si0.5P0.5, Ti2.25Co0.75Si0.5As0.5, and Ti2.25Co0.75Si0.5Sb0.5 are spin-gapless semiconducting materials. The introduced impurity atoms may adjust the valence electron configuration, change the charge concentration, and shift the location of the Fermi level.

“…Heusler type alloys which are ternary intermetallics, were discovered first by Friedrich Heusler in the early 20th century [1]. There is two type Heusler alloys which are called half-Heusler are given XYZ and full-Heusler alloys are given X2YZ general formulas, respectively.…”

Full-Heusler Fe3M (M=Al, Ga, Si and Ge) alloys whose crystal structure is DO3-type disordered structure which conforms to 3 ̅ space group, have been investigated by using Local Spin Density Approximation (LSDA) and Generalized Gradient Spin Approximation (GGSA) in the Density Functional Theory (DFT) as implemented in VASP (Vienna Ab initio Simulation Package) software. After the examination of ground states of our materials in DO3-type structure, their full structural, mechanical properties and electronic band structures have been investigated and made comparison between LSDA and GGSA. The calculated electronic band structures and total electronic density of states (DOS) within both of two approximation show that these alloys have metallic behavior. The calculated elastic constants and estimated mechanical properties depended on these constants indicate that these alloys are stable mechanically and have anisotropic behavior.
