Abstract

We report the out-of-plane and in-plane magnetic susceptibility and resistivity of Ni-doped La1.99Sr0.01CuO4 single crystals grown by Traveling-Solvent Floating-Zone technique. Our data shows that in lightly Sr-doped compounds the Néel temperature TN increased with increasing Ni concentration. At high temperatures, the resistivity is described within the impurity band conduction model. As the temperature is lowered, the resistivity behavior change to the variable range hopping model associated with the evolving of antiferromagnetic ordering.
