Abstract
Linear magnetoelectric effect (ME) in epitaxial iron garnet films of (YBiPrLu)3 (FeGa)5O12 composition has been studied by means of optical polarimetric method with spatial resolution ∼2.5 μm. The measurements were carried out in both longitudinal H∥E and transversal H⊤E geometry for films grown on the substrates of (111) and (210)-orientation. The magnitude of ME effect within individual magnetic domain and originated from domain wall movement is evaluated. The strong anisotropy of ME effect in transversal geometry in (210)-films was observed in the regime of rotation of magnetization. The electric field induced changes of magnetic anisotropy parameters responsible for the observed effects are evaluated.
