Thermodynamics and Magnetism of YCo5 Compound Doped with Fe and Ni: An Ab Initio Study

“…It has been explored both experimentally and theoretically in the past due to its unique qualification as a "gap" permanent magnetic material [5,. Actually, almost all experimental papers on the YCo 5 magnet have been dedicated to studying MAE of the undoped magnet as well as doped with Sm, Nd, Ge, Fe, Cu, and Ni [5,[10][11][12][13][14][15][16][17][18][19][20][22][23][24][25][26][27][28][29][31][32][33][34][35][41][42][43][52][53][54]62,66,70,[72][73][74]77,80]. MAE, the Curie temperature, and the energy product, which are 5.7 MJ/m 3 , 921 K, and 224 kJ/m 3 , correspondingly, were first reported in refs.…”

“…Furthermore, Fe is a ferromagnetic metal with a very substantial magnetization at room temperature (1.76 MA/m [7]). The YCo 5 magnet doped with iron has been the subject of numerous experimental papers [13,18,20,34,35,41,42,52,72,73,80]. Replacing all cobalt with iron to enhance magnetization in the YFe 5 compound produces a thermodynamically unstable phase, which is not experimentally observed within the equilibrium Y-Fe phase diagram.…”

“…Second, YCo 5 remains an interesting magnet in its own right, being free of lanthanide elements [37], having an anisotropy field of order 20 T [38] and potentially having a coercivity comparable to traditional SmCo 5 magnets [39]. Indeed, Fe-doped YCo 5 magnets are the subject of active research as potential intermediate-performance permanent magnets [40].…”
