摘要The lattice distortion of tetragonal Cu2Sb-type Mn1.95V0.Sb-05 alloy was realized by Li interstitial doping or hydrostatic pressure. The metamagnetic transition temperature was decreased and the thermal hysteresis was widened by either depressurization or increasing interstitial Li content. Its effects on magnetic entropy changes (AS) and critical field had been studied. Thanks to moderate hydrostatic pressure, the beneficial enhancement of maximum of AS was achieved in tetragonal Cu2Sb-type Mn1.95V0.05Sb alloy. Our experiment demonstrates that the interatomic distance between Mn-II-Mn-II sites and the electronic density surrounding Mn-II sites are critical for metamagnetic phase transition.
