Lattice distortion tuning of the metamagnetic phase transition in tetragonal Cu2Sb-type Mn1.95V0.05Sb alloy

Magnetotransport and magnetic properties of Cr-modified Mn2Sb epitaxial thin films

“…Hydrostatic pressure and interstitial Li doping have been employed to control the lattice volume and thereby modify the magnetic entropy, thermal hysteresis window, and magnetic phase transition temperature of the Mn 1.95 V 0.05 Sb alloy. 8 Moreover, doping with low melting point semimetal of Bi introduces self-assembled grain boundary precipitates, which enhances the magnetoresistance (MR) and magnetic entropy, 9 and in bonus, enhances the magnetostrain effect. 9–12 Very recently, Nabi et al observed a giant composition-tunable topological Hall effect up to ∼250 K in Mn 2– x Zn x Sb single crystals, which is caused by topological magnetic spin texture, suggesting that Mn 2 Sb-based compounds are good candidate materials for studying topological magnetism.…”

Low-field reversible magnetocaloric effect in Co-dopedMn-Cr-Sb alloys

“…近年来研究发现, Co掺杂的Mn-Co-Sb合金能够消 除铁磁MnSb杂相, 且能够获得亚铁磁-反铁磁的一级 磁-弹性相变 [18][19][20][21][22] , 从而能够显示出显著的磁热效应. [19,20,23,24] , 如图3(b)所示. 同时注意到, 5 T磁场下的 热温变与文献中报道的Mn 2 Sb基合金和NiMn基Heus-ler合金的结果进行了对比 [11][12][13][26][27][28] .…”
