Abstract
Hexagonal Dy0.5Y0.5MnO3, a multiferroic rare earth manganite with geometrically frustrated antiferromagnetism, has been investigated with neutron diffraction measurements. Below 2.4 K magnetic order is observed on both the Mn (antiferromagnetic) and Dy (ferrimagnetic) sublattices that is identical to that of undilutaed hexagonal DyMnO6d3^. The Mn moments undergo a spin preorientation transtion between 3.4K and 10K, with antiferromagnetic order of the Mn sublattice persisting up to 70 K; the antiferromagnetic order in this intermediate tempearture phase is distinct from that observed in undiluted (h)DyMnO3 or other (h)RMnO6d3^ materials with a magnetic R ion. A magnetic field applied parallel to the crystallographic c-axis will drive a transitionfrom the intermediate temperature antiferromagnetic phase into the low temperature ferrimagnetic phase with relatively little hysteresis.Citation
