Abstract

Ferroelectric and magnetic properties of Fe-doped potassium-sodium tantalate niobate (K _0.5Na _0.5(Nb _0.95Ta _0.05) _1-xFe _xO _3-x; x = 0 and 0.01) ceramics prepared by the conventional sintering method were investigated. In comparison with pure ceramics, the 0.01 Fe-doped ceramics show magnetic and ferroelectric properties simultaneously at room temperature. The relative dielectric constant significantly decreases after applying a magnetic field for the Fe-doped ceramics, indicating the coupling between ferroelectric and ferromagnetic orders. Magnetocapacitance of -0:77% was observed at room temperature and 50 kHz by the application of a magnetic field of 5000 Oe.
