“…34,52 At T C the spinfluctuation scattering becomes suppressed when a moment is induced on the Co sites due to the presence of an effective field. The latter is caused by the appearance of a molecular field due to the spontaneous alignment of the R ions.…”

“…This in turn leads to the negative values of ⌬(T) below T C occasionally observed. 34,52 In order to trace the effect of pressure on the temperaturedependent resistivity we have applied this procedure to our measured data, where (T) of LuCo 2 at ambient pressure only has been taken as a reference. Figure 9 depicts ⌬(T, P) of ErCo 2 and HoCo 2 .…”

“…To explain the resistance results we propose the following scenario. Above T C , in RCo 2 , the resistivity is governed by spin-disorder scattering of conduction electrons on the paramagnetic rare-earth moments and on spin fluctuations arising mainly from local splitting of the cobalt 3d band (Duc et al 1991, Gratz et al 1995. When the temperature is lowered, the 4f moments which order ferromagnetically at T C yield a strong molecular field in the material.…”

“…Significant modifications in the temperature dependence of the electrical resistivity, susceptibility and thermopower were observed in RCo 2 [1][2][3][4][5], pseudobinary (R 1Àx Y x )Co 2 [1,2,[6][7][8][9][10][11][12] and LR 1Àx HR x Co 2 (LR ¼ light rare earth and HR ¼ heavy rare earth) [13][14][15] compounds depending on the type of rare earth element and concentration of substituting second rare earth or non-magnetic Y. Up to now detailed study of the behaviour of both rare earth and Co magnetic subsystems with Y-substitution is performed for the R 1Àx Y x Co 2 compounds with R ¼ Dy, Er, Ho, Tb, Gd.…”
