“…Mn 2 NiGa [21] and Mn-Pt(Pd/Rh)-Sn [22,[46][47][48]. Interestingly, skyrmions have also been observed in the centrosymmetric Ni 2 MnGa Heusler compound [37], which exhibits magnetic shape memory effect [49,50] and several other fundamental properties like giant negative magnetoresistance (MR) [51][52][53], large magnetocaloric effect [54,55], AHE [56,57], anomalous Nernst effect [58], etc. The stoichiometric Ni 2 MnGa magnetic shape memory alloy (MSMA) shows both FM and ferroelastic (martensite and premartensite) phase transitions [59,60].…”
