Sensitivity of domain walls of bismuth-substituted iron garnets to a magneto-electric interactions caused by external complex field influence

摘要

We revealed the "smearing" effect of domain walls' local areas under conditions with the joint impact of AC and DC electric fields in inhomogeneous magnetic structures of bismuth-substituted iron garnet films. Magneto-optical measurements and the direct visual observations in transmitted light were used for the investigation. The revealed effect depends essentially on the curvature of the domain walls and occurred visually only when an external magnetic field of certain orientation was applied to the sample.
