Effet Hall et propriétés magnétiques des films de nickel déposés et étudiés sous ultra-vide

Thickness variations in extraordinary and spontaneous Hall coefficients of iron films

“…Some studies [16,[19][20][21][22][23][24][25][26][27][28][29] have therefore been carried out to determine both the ordinary Hall coefficient (OHC) RH, the extraordinary Hall coefficient (EHC) R, and the saturation magnetization Mg. Most of these published data [20,21,22,24,25,28,29] study the change in EHC with temperature T ; the thickness dependence of the EHC has also been studied by Vautier [22], Le Bas [24], Coren et al [16]; recently Wedler et al [27] reported an unexpected oscillatory behaviour of the OHC and EHC.…”
