Abstract

The magnetic properties of the YbCrCO₄ oxide have been studied by both bulk magnetic measurements and ¹⁷⁰Yb Mössbauer spectroscopy. Ferrimagnetic ordering is shown to be present below 25 K, driven by the exchange within the chromium sublattice. In the saturation state, the magnetic moment is 0.55 μ_B for Yb³⁺, and presumably 1 μ_B for Cr⁵⁺, the two sublattices being antiferromagnetically coupled. The anisotropic Yb-Cr exchange polarises the Yb³⁺ sublattice below 25 K, so as to force the Yb magnetic moments to lie in the hard magnetic a-b plane.
