Abstract

Magnetocapacitive effects were investigated for Néel's N -type ferrimagnetic SmMnO3, which shows temperature-induced magnetization reversal at the compensation temperature (Tcomp =9.4 K) in a low magnetic field B (<∼1 T). When higher B is applied, remarkable anomalies were observed in the temperature profiles of magnetization, dielectric constant, and dielectric relaxation time around Tcomp. These coupled field-induced anomalies give rise to striking magnetocapacitance and could be attributed to simultaneous reversals of ferrimagnetically coupled Sm and Mn moments. In addition, peculiar cooling-field dependent asymmetric magnetocapacitance was observed at Tcomp.
