1.4. ME effect at magnetic resonance
ME composites also offer important applications in the microwave range. In this frequency range, the ME effect reveals itself as a change in the magnetic permeability under an external electric field. Investigations of FMR line shift by an applied electric field are easily performed for layered ferrite–piezoelectric structures. In addition, layered composites are of interest for applications as electrically tunable microwave phase shifters, devices based on FMR, magnetic-controlled electro-optical and/or piezoelectric devices and electrically readable magnetic memories.
In this chapter, we discuss theoretical models of multilayer ME composites in the microwave range (Bichurin et al., 2001
