Abstract

Magnetostriction was investigated for layered A-type antiferromagnetic SmMnO 3 showing large magnetocapacitive effects around a temperature (T TP) where ferrimagnetically coupled Mn 3d and Sm 4f moments were reversed simultaneously. Upon sweeping temperature or a magnetic field, a significant lattice distortion was observed at T TP or the coercive field, respectively. This indicates that the lattice is strongly coupled with the magnetic configuration. We discuss the lattice distortion accompanied by the magnetization reversal in terms of a partial change in the orbital state of Mn e g electrons.
