Abstract:

The behaviour of the electrical resistivity-rho of Lu(Co1-xAlx)2 and Lu(Ni1-xAlx)2 has been studied as a function of the aluminium concentration, temperature and applied magnetic field. In the Pauli paramagnet LuCo2 a larger value of the residual resistivity rho(res) than in LuNi2 and the tendency to saturation of the rho(T) dependence at temperatures T> 150 K are observed. In LuNi2, in which the exchange enhancement has not been observed, residual resistivity increases monotonically with increasing aluminium substitution on nickel sites. The concentration dependence of rho(res) in Lu(Co1-xAlx)2 shows a maximum at x = 0.08 near the critical concentration for the onset of ferromagnetism. The difference in behaviour of these two systems is explained by a large contribution to the electrical resistivity from spin fluctuations and by a change in this contribution with changes in the aluminium content, temperature and magnetic field.
