Magnetization, Electrical Resistivity, Thermopower, and Neutron Diffraction in HoCu₂

Abstract

Abstract HoCu 2 shows a Curie‐Weiss susceptibility above 15 K. The paramagnetic moment and the paramagnetic Curie temperture is (10.1 ± 0.1) μ B / H 0 and (4 ± 2) K, respectively. Two cusps (at about 7 and 10 K) are seen in the magnetization versus temperature curve. These cusps reflect a change of the magnetic structure and the Néel temperature. The influence of conduction electron scattering on the localized 4f moments is estimated for the resistivity and the thermopower. Neutron diffraction measurements show that the antiferromagnetic structure is incommensurate with the crystal lattice.
