In this presentation, we report the results of the direct (P-H) and inverse (M-E) magnetoelectric effects in Y-type hexaferrites with different Sr doping levels. Using the combination of high electric and magnetic fields, we investigate the isothermal switching between two ME states. We discuss these new findings in terms of a possible way to evaluate the stability of the ME state in multiferroic materials.
