A cost-effective self-biased magnetoelectric effect in SrFe₁₂O₁₉/Metglas/Pb(Zr,Ti)O₃laminates

By introducing the hard magnetic SrFe12O19 ribbon, a self-biased magnetoelectric laminate—SrFe12O19/Metgals/Pb(Zr,Ti)O3 was successfully designed. Without any external magnetic field, the laminates exhibit giant self-biased ME responses of 1 V (cm Oe)−1 at quasi-static condition, and up to 29 V (cm Oe)−1 at high-frequency resonance. The induced ME voltage shows a good linear relationship to the applied ac magnetic field with amplitude as low as 10−8 T at 1 kHz, and the self-biased ME property presents an outstanding stability in a time span of 12 months.
