Influence of Al-atoms on the spin fluctuation scattering in R(Co, Al)2 compounds
The resistivity and magnetisation have been measured for the R(Co1-xAlx)2 compounds with R = Nd, Gd, Tb, Dy, Ho, Er and Lu. For x = 0.2 the resistivity enhancement is observed below Tc however, for the compounds with R = Lu-Tb only. The results are discussed in terms of the spin fluctuation scattering and indicate that the enhancement of the spin fluctuation scattering is strongly related to the lattice parameter. © 1992.
