Zinc-blende compounds of transition elements with N, P, As, Sb, S, Se, and Te as half-metallic systems

Abstract

We report systematic first-principles calculations for ordered zinc-blende compounds of the transition metal elements V, Cr, Mn with the sp elements N, P, As, Sb, S, Se, Te, motivated by recent fabrication of zinc-blende CrAs, CrSb, and MnAs. They show ferromagnetic half-metallic behavior for a wide range of lattice constants. We discuss the origin and trends of half-metallicity, present the calculated equilibrium lattice constants, and examine the half-metallic behavior of their transition element terminated (001) surfaces.

Antiferromagnetic dipolar ordering in[Co2MnGe∕V]Nmultilayers

“…CrSe) and pnictides (e.g. CrAs) in the zinc-blende or wurtzite structures [58], the diluted magnetic semiconductors (e.g. GaAs or ZnO doped with magnetic transition metal ions) [5,6] and the fully spin polarized Heusler alloys.…”

Electronic, optical, and thermoelectric properties of Fe2+xV1−xAl

“…[6][7][8][9][10][11][12] Atomistic characterization of the different properties is ascribed to e.g., crystal field splitting, electron correlation, and the d bandwidth. Of particular interest in the Heusler-alloys is the Fe-based family, e.g., Fe 2 VAl where Fe antisite can induce emerging phenomena, e.g., a para-to-ferromagnetic phase transition.…”

Observation of room temperature ferromagnetism in ZnTe:Cr films grown onto glass substrate by thermal evaporation method

“…An obvious hysteresis loop is observed in the lower field region of M vs H plot confirming a ferromagnetic ordering induced by the Cr doping in ZnTe. ferromagnetic with Curie temperature above room temperature and it plays a key role in the ferromagnetic behavior of ZnTe:Cr films [26][27][28][29]. It is therefore concluded that the presence of zincblende ZnCrTe phase along with CrTe precipitates shall be the reason for the observed ferromagnetic behavior in the low field region at all the measured temperatures 5, 77 and 300 K.…”
