摘要

We discovered that an external magnetic field does induce a ferroelectric phase in Mn0.9 Fe0.1 W O4 below T1 =12 K. The spontaneous polarization appears along the b axis upon applying a magnetic field above 4 T. The temperature and magnetic field dependencies of the spontaneous polarization show a strong coupling between the magnetic and ferroelectric orders. We correlate the ferroelectric transitions with dielectric constant and magnetization anomalies. Our results are interpreted in terms of recent theories relating the magnetic order induced ferroelectricity in multiferroic compounds to the inversion symmetry breaking effects of unconventional magnetic structures.
