Abstract
The first observation of magnetic resonance field shifts proportional to an applied electric field in a magnetically ordered material is reported. It involves ferromagnetic resonance experiments on lithium ferrite crystals in an applied electric field at temperatures between 4.2 and 77°K. The observed shifts are predicted by using statically measured values of the electric field derivative of the uniaxial anisotropy energy existing in the "skin" region of these crystals.Keywords
