Preparation, structural and magnetic characterization of DyCrMnO5

DyCrMnO5 is isostructural with DyMn2O5, belonging to the Pbam space group. The crystal structure contains infinite chains of edge-sharing Mn4+O6 octahedra, interconnected by dimer units of Cr3+O5 square pyramids. The low-temperature neutron powder diffraction (NPD) patterns do not show any magnetic contribution, indicating that a full long-range magnetic ordering is not established down to low temperature, although the Dy3+ magnetic moments are susceptible to be polarized by an external magnetic field at the lowest temperature of 5 K.
