Specific heat, magnetic susceptibility and electrical resistivity measurements on LaNiO3

Abstract

Measurements of specific heat, magnetic susceptibility and electrical resistivity on LaNiO3 are reported. No evidence of magnetic ordering or metal-insulator transitions is found. From the measured electronic specific heat parameter γ and the Pauli susceptibility χP, a Stoner enhancement parameter is derived. Comparison with band structure calculations performed by other workers is also made.
