Description

We have measured 57Fe Moessbauer spectra of CaV0.9957Fe0.01O3 in the region from room temperature to liquid helium temperature for a detailed research of magnetic properties of CaVO3. The magnetic susceptibility of this oxygen stoichiometric sample indicates a small antiferromagnetic-like kink around 170 K but the Moessbauer spectra have two paramagnetic contributions in the entire temperature region. One is a strong single line attributed to Fe3+ and the other is a weak doublet with a large eqQ splitting attributed to Fe2+. The results suggest that the magnetic susceptibility anomaly at 170 K is not related to a magnetic transition but to some kind of structural transition. (orig.)
