Magneto-Electric Effects on Sr Z-type Hexaferrite at Room Temperature

, 2011
In this paper, magnetoelectric effects of Sr Z-type hexaferrite, Sr3Fe24Co2O41, at room temperature is measured. The change in remanence magnetization was measured by applying a DC voltage or electric field across a slab of hexaferrite.
