Abstract
The magnetic-field dependence of the ferroelectric polarization and the spin-lattice coupling in multiferroic $\mathrm{Mn}\mathrm{W}{\mathrm{O}}_{4}$ have been investigated. The ferroelectric transition from the low temperature paraelectric phase occurs when the magnetic field is applied along the $a$, $c$, and the spin easy axes. The ferroelectric polarization in the magnetic field along the $a$ and the $c$ axis shows a contrasting behavior depending on the field direction, possibly reflecting the relative configuration between the crystallographic axis and the magnetic principal axis in the $ac$ plane. Incommensurate lattice modulation observed in the ferroelectric spiral-spin phase confirms the existence of spin-lattice coupling in $\mathrm{Mn}\mathrm{W}{\mathrm{O}}_{4}$. The lattice modulation indicates that the ferroelectric AF2 phase also takes the incommensurate magnetic structure in a magnetic field. In the high-field phase, which appears in high magnetic fields above $12\phantom{\rule{0.3em}{0ex}}\mathrm{T}$ along the easy axis, the magnetic-field-induced ferroelectric polarization disappeared.
