Modulation of magnetic properties and enhanced magnetoelectric effects in MnW1–xMoxO4 compounds.

In this letter, we investigate the magnetic and ferroelectric properties of polycrystalline MnW1–xMoxO4 (x = 0, 0.05, 0.10, 0.20) compounds. The substitution of nonmagnetic Mo6+ ions for W6+ ions modifies the magnetic transition temperatures of MnW1–xMoxO4 by changing the Mn—O—Mn bond. As a result, distinct ferroelectric properties and enhanced magnetoelectric effects are observed in Mo6+ -doped MnWO4 compounds. The effects of substitution of Mo6+ ions on magnetic properties and magnetoelectric coupling are discussed. [ABSTRACT FROM AUTHOR]
