“…As early as 1966, FeRh alloy was reported to have a large total entropy change due to magnetic phase transition [1]. Along with the magnetic transition, materials usually exhibit novel performance [2][3][4][5][6][7], such as the giant magnetoresistance in Gd 7 Rh 3 [8], FeRh [9,10], Bi-doped Mn 2 Sb [11] and Ni doped FeRh [12], giant magnetocaloric effect in Gd-Si (Nd)-Ge [13,14], MnZnSb [15], FeRh [16,17] and Ni-Mn-Fe-Sn [18], and exchange bias (EB) in Fe 2 MnGa [19], Mn 2 PtGa [20]. and Sn) alloys have been extensively studied due to their excellent properties, such as the large anomalous Hall effect (AHE), topological Hall effect (THE), Nernst effect, EB effect and magneto-optical Kerr effect [21][22][23][24][25][26][27][28].…”
