Electronic and magnetic properties of a new heavy-fermion compound, CeRuSn₃

Abstract

Measurements of electrical resistivity, Hall coefficient, thermoelectric power, magnetic susceptibility and specific heat have been made on CeRuSn3 with cubic Pm3n structure. The results indicate that CeRuSn3 is a new heavy-fermion compound with a specific heat coefficient of 1.4 J mol-1 K-2 at 0.6 K. Above 0.6 K, it shows no magnetic ordering.
