“…10,11,[14][15][16] In previous papers, we proposed a theoretical model that explains the anomalous variations of low-temperature conduction with composition x, magnetic field B, and pressure P in Y 1Àx R x Co 2 alloys. 10,[16][17][18] A random distribution of magnetic R and nonmagnetic Y ions over the rare-earth sublattice in Y 1Àx R x Co 2 alloys creates spatially fluctuating effective field B eff ðrÞ ¼ B þ n fd M R ðrÞ acting on the 3d electron subsystem [here, B is the external magnetic field, M R ðrÞ the 4f magnetic moment at site r of the rare-earth sublattice, and n fd the 3d-4f exchange constant]. This field can be characterized by the distribution function FðB eff Þ.…”
