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

DOI

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.
