Abstract
An orthorhombic DyMnO3 single crystal has been studied in magnetic fields up to 14T and between 3K and room temperature. The field dependent ordering temperature of Dy moments is deduced. The paramagnetic Curie Weiss behavior is related mainly to the Dy3+sublattice whereas the Mn sublattice contribution plays a secondary role. DC magnetization measurements show marked anisotropic features, related to the anisotropic structure of a cubic system stretched along a body diagonal, with a magnetic easy axis parallel to the crystallographic b axis. A temperature and field dependent spin flop transition is observed below 9K, when relatively weak magnetocrystalline anisotropy is overcome by magnetic fields up to 1.6T.
