Abstract
The effect on electrical and magnetic properties of Gd3+ doping of LaN iO3 was studied for Gd concentration x less than or equal to 0.1. The electrical resistivity rho increases with x, being d rho/dT>0 for all samples studied. The magnetic susceptibilities were fitted by the func tion (chi)(T) = (chi 0) - aT(2) + xC(Gd3+)/T. The EPR results are disc ussed in terms of the Gd3+ paramagnetic moment interactions with the c rystal field and with the conduction electron spins.
