“…Ferromagnetic (FM) coupling occurs if these rare earths are either light or heavy, while antiferromagnetic (AF) coupling is induced when A and B are light and heavy rare earth ions. Additionally, the inverse MCE can be observed, as in the case of (Pr,Gd)Al 2 [3], which in turn can induce compensation points, i.e., temperatures where the net magnetization is zero, as well as an exchange bias(EB)-like effect as in Ho 0.25 Nd 0.75 Al 2 [4] and Gd 0.25 Pr 0.75 Al 2 [5]. Consequently, other than magnetic refrigeration at low temperatures, these materials show a great potential for numerous applications such as information storage technology devices, magnetic random access memory, and magnetic field sensors [1,2,[6][7][8][9][10][11].…”
