【 摘 要 】

The magnetic properties of the YbCrO4 oxide have been studied by both bulk magnetic measurements and Yb-170 Mossbauer 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 mu(B) for Yb3+, and presumably 1 mu(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 h plane. (C) 2004 Elsevier B.V. All rights reserved.
