Frequency-dependent magnetoelectricity of CoFe 2O 4-BaTiO 3 particulate composites
Abstract
CoFe <inf>2</inf>O <inf>4</inf>-BaTiO <inf>3</inf> particulate composites were prepared by wet ball milling method, their magnetoelectric (ME) effect was studied as a function of their constituents and modulation frequency. The results show that the ME coefficient increases as a function of modulation frequency from 400 to 1000 Hz and the ME characteristics of ME curves are also modified because the electrical conductivity of the CoFe <inf>2</inf>O <inf>4</inf> phase is sensitive to the increase in frequency between 400 and 1 000 Hz. The third phase Ba <inf>2</inf>Fe <inf>2</inf>O <inf>5</inf> formed during the sintering tends to reduce the ME effect. © 2011 The Nonferrous Metals Society of China.
