From: Nonlinear magnetoelectric effects in Al-substituted strontium hexaferrite

Characterization of magnetic and electric properties of hexaferrite materials in the case of SrFe12O19. Frequency vs. field dependence for magnetostatic modes of strontium hexaferrite sample in multidomain and saturated states. Symbols represent the data and dashed lines are theoretical estimates. Inset shows current–voltage characteristic of the given hexaferrite sample.
