Magnetic and exchange studies in amorphous $\mathsf{Co_{80-x}Ho_xB_{20}}$ alloys

Magnetic and anisotropy studies in amorphous Co80−xHoxB20 alloys

“…e factor and the mean field at site i; respectively. Values of J Co2Co and J Co2Ho deduced from this analysis (detailed elsewhere [7]) appear in Table 1. From the same analysis, Idzikowski has determined the values of exchange integrals relative to amorphous Co-Tb-B alloys [18].…”

“…The analysis of the approach of the magnetization to magnetic saturation, based on the latter model, permits the determination of several magnetic parameters, such as the local random anisotropy constant, the exchange field and the ferromagnetic correlation length. Recently, magnetization studies have been performed on amorphous Co 80Àx Ho x B 20 [6,7]. The aim of this paper is to study magnetic and anisotropy properties of these alloys and compare these properties with those of other TM-RE alloys.…”
