Abstract
Powdered and single crystal specimens of dysprosium manganate, DyMn2O5, have been studied by neutron diffraction at temperatures between ambient and 4.2K. Magnetic transitions are observed at 44K, 18K and 8.4K. Both manganese and dysprosium moments are ordered below 8.4K, where the magnetic structure has been refined. Measurements above 8.4K indicate that this transition is to a second phase in which both moments are again ordered, but the details of the structure of this phase are not yet known. The relationship of the low-temperature phase to the magnetic structure of some isomorphous rare-earth manganates is discussed.Keywords
