Magnetocaloric effects in Ni–Mn–X based Heusler alloys with X=Ga, Sb, In

Magnetoresistance and magnetocaloric effect at a structural phase transition from a paramagnetic martensitic state to a paramagnetic austenitic state in Ni50Mn36.5In13.5 Heusler alloys

“…[6][7][8] However, these systems possess large hysteresis losses and are therefore less effective from an application point of view.…”

Phase Transitions and Magnetocaloric Properties in MnCo1−xZrxGe Compounds

“…Therefore, the developments of new materials that show large MCEs are essential. To date, the largest MCEs have been reported in materials such as Gd 5 Si 2 Ge 2 [3], MnFe(P,As) [4], LaFe 13− Si [5], NiMn(Ga,Sb,In) based Heusler alloys [6], and MnAs 1− Sb [7], which all show firstorder crystallographic and magnetic phase transitions simultaneously, that is, magnetostructural transitions (MSTs). Hence, the exploration and study of the new materials that exhibit MSTs is important for applications and fundamental physics.…”

“…Among them, Gd 5 (Si x Ge 1-x ) 4 [1,16], La(Si,Fe,X) 13 (X= Co, Mn) [17,18], MnFe(P,X) with X = As, Ge, Si [6,19], non-stoichiometric NiMn-X-based Heusler-type (X= Ga, Sn, In, Sb) [20][21][22][23][24][25][26] or Mn(Co,Ni)Ge-based alloys [27][28][29][30][31][32][33][34][35][36][37]. It is worth noting that MnCoGe-based alloys have one of the largest contributions of S st to S T , giving rise to one of the highest reported GMCE in terms of the maximum value of S T [14].…”
