Anisotropic Magnetic Property of Kondo Lattice Substance: CeCu₆

Abstract

We have measured the electrical resistivity, magnetoresistance, magnetic susceptibility and magnetization of CeCu 6 in the temperature region of 0.6 K to room temperature. The magnetic property is extremely anisotropic, reflecting the orthorhombic crystal structure. The anisotropy of negative magnetoresistance can be qualitatively understood by the corresponding magnetization. We have found that CeCu 6 is a typical Kondo lattice substance, having no magnetic ordering. The Kondo temperature is estimated as 2–3 K.
