Abstract

In order to reveal the relationship between the appearance of ferroelectricity of RMn2O5 and magnetic ordering, we have measured the ferroelectric P-E hysteresis loops and investigated the temperature dependence of the electric polarization of TmMn2O5. Strange P-E loops were observed, and a pyroelectric response was observed even on zero field cooling. The causes of both strange phenomena are unknown, but the temperature-dependent tendencies of the polarization and of the coercive field corresponding to the magnetic phase diagram were observed.
