Abstract

We report the out-of-plane and in-plane magnetic susceptibility and resistivity of Ni-doped La_2-xSr_xCuO₄ single crystals. Our data shows that in lightly Sr doped compounds the Néel temperature T_N increased with increasing Ni concentration. As the temperature is lowered, the resistivity deviates from the impurity band conduction process and becomes dominated by the variable range hopping process associated with the evolving of antiferromagnetic ordering.
