Abstract
The report is on room temperature nonlinear current-induced magnetoelectric effect in single-crystal Y-type hexaferrite with collinear magnetic structure. The effect was observed at microwave frequencies and resulted in 1.1-to-1.4 GHz ferromagnetic resonance frequency shift of Ba2Zn2Fe12O22 ferrite resonator with application of an in-plane DC current. From the experimental results we estimated the magnetoelectric modification of effective saturation magnetization and found that it scales linearly with applied electric power. A phenomenological model of this effect, which accounts for hexaferrite’s crystallomagnetic symmetry, was proposed to explain the observed dependence. These results are of importance for the application of Y-type hexaferrites in electrically tunable planar microwave signal processing devices.
