Abstract
Abstract The crystal structure of magnetoelectric KNiPO4 was refined by single crystal X-ray diffraction methods at room temperature confirming orthorhombic space group Pna21. Powder neutron diffraction investigations showed that the room temperature structure is preserved down to 30 K. Consistent with magnetic susceptibility measurements, long-range antiferromagnetic ordering according to K = 0 and Shubnikov space group Pna21 is established by neutron diffraction at temperatures below T N = (25.5 ± 0.5) K. The ordered magnetic moments of (3.00 ± 0.04) μg, oriented along [1, 0, 0], indicate large orbital contributions to the magnetic moment of Ni2+. DTA studies in the temperature range from 100–1000°C, showed two phase transitions, at 486.5°C and at 581.3°C.
