Abstract

To understand the rotation phenomenon of ferroelectric polarization ( $\vect{ P}$ ) controlled by a magnetic field ( $\vect{ h}$ ), which is currently of great interest in experiments, the variation of the magnetic and ferroelectric behaviors under rotating $\vect{ h}$ are investigated by Monte Carlo simulation on a three-dimensional spinel lattice with classical Heisenberg spins. The anisotropic behaviors are observed for the different paths in which $\vect{ h}$ rotates. Especially when $\vect{ h}$ rotates in the plane normal to the magnetic modulation vector, $\vect{ P}$ can be driven by $\vect{ h}$ to rotate continuously without any noticeable decay. The detailed analysis of the spin structure indicates that the conical spin order is always retained very well during the process of $\vect{ h}$ rotation, and the continuous rotation of $\vect{ P}$ is realized by $\vect{ h}$ rotating the magnetization ( $\vect{ M}$ ), and then rotating the conical spin structure.
