On the Problem of the Staggered Field in CuGeO3 Doped with Magnetic Impurities
S. V. Demishev
Abstract
The magnitude of the staggered field is calculated from the EPR data for CuGeO3 doped with Co and Fe magnetic impurities. It is found that this parameter demonstrate an anomalous temperature and magnetic field dependence probably due to (i) the specific mechanism of the staggered field generation in doped CuGeO3 and (ii) a competition between antiferromagnetic interchain exchange and staggered Zeeman energy.
