Lett. 92, 262502 (2008); http://dx.doi.org/10.1063/1.29528280003-6951http://hdl.handle.net/10919/25176Giant magnetoelectric coupling at both microwave frequencies and dc was observed in an FeGaB/lead magnesium niobate-lead titanate microwave multiferroic composite. A record high microwave frequency tunability of Delta f=900 MHz or Delta f/f=58% was demonstrated with the change of an external electric field from -6 to +2 kV/cm. A strong electric field dependence of magnetic hysteresis loops was also observed. Such multiferroic composite provides great opportunities for electrostatically tunable microwave devices.
