Modulated multiferroic properties of MnWO4via chemical doping

Here we prepare polycrystalline Mn 1− x Ni x WO 4 ceramics with x = 0, 0.02, 0.04, 0.06 for investigating their magnetic, ferroelectric, and multiferroic properties.

Description
Summary:Here we prepare polycrystalline Mn 1− x Ni x WO 4 ceramics with x = 0, 0.02, 0.04, 0.06 for investigating their magnetic, ferroelectric, and multiferroic properties. The Ni 2+ -substitution gradually expands the lattice and modifies the magnetic performance with increasing x , resulting in a strong modulation of electric properties of those samples. For Mn 0.96 Ni 0.04 WO 4 , ferroelectric polarization is observed in the whole temperature regime below T AF2 , and is well modified by an external magnetic field, which is discussed under the framework of a spin-current model in this manuscript. Here we prepare polycrystalline Mn 1− x Ni x WO 4 ceramics with x = 0, 0.02, 0.04, 0.06 for investigating their magnetic, ferroelectric, and multiferroic properties.
