Description
Summary:Charge transfer type Nd1/3Sr2/3FeO3 was synthesized and its magnetic properties were investigated by neutron diffraction and Mössbauer spectroscopy at various temperatures ranging from 4.2 K to room temperature. The powder neutron diffraction shows magnetic ordering structures. The Nd1/3Sr2/3FeO3 with small lattice distortion underwent a charge ordering (CO) phase transition at and below TCO=163 K corresponding to a sequence of Fe+3Fe+3Fe+5Fe+3Fe+3Fe+5 aligned along the z direction of rhombohedral, as well as canted antiferromagnetic spin ordering. The spin rotation resulting from helical spin of Nd was observed at and below 25 K. At 4.2 K, the electric quadrupole splittings for Fe3+ and Fe5+ are 0.06 and 0.15 (mm/s) which were changed to −0.06 and −0.02 (mm/s) at and above 20 K. It is evidence of spin rotation in Nd1/3Sr2/3FeO3.
