Abstract :
We report on the giant magnetoelectric effect in Y-type hexaferrite Ba0.5Sr1.5Zn2(Fe1−xInx)12O22 (x=0.08). Large electric field tuning of magnetism is observed near room-temperature. Electrically controlled magnetization reversal is observed at 315 K. The sign of the magnetization exhibits an on–off behavior with the electric field. The scanning probe microscopy results show direct and powerful evidence of electric control of magnetism at room temperature.
