Understanding low temperature Nd ordering and double magnetization reversal in NdFeO3, perovskite

Abstract: We aim to understand magnetization reversal phenomenon, observed in the NdFeO3 perovskite, by deriving the evolution of Nd3+ and Fe3+ moments ordering from neutron diffraction study in the temperature range of 50 – 1.5 K by using the GEM diffractometer. Our dc magnetization study shows Fe3+ spin reorientation over~180 -120 K, consistent with the literature. Interestingly, for the first time, magnetization reversals from positive to negative at 6.3 K and then negative to positive at 4.3 K, resulting in double magnetization compensations have been found. The correlation of this peculiar observation with rare-earth (Nd) ion ordering has not been understood so far. The outcome of the proposed study would be essential to give a first microscopic understanding of the double magnetization reversal phenomenon which has potential for its application in magnetic memory and spin resolving devices.
