Abstract

The effect of a controlled ion beam pre-treatment of (1 1 1)-oriented Gd₃Ga₅O₁₂ substrates on the magneto-optical properties and surface morphology of the ultrathin bismuth-substituted yttrium–iron garnet films with a composition Bi_2.8Y_0.2Fe₅O₁₂ was studied. It has been shown that the observed sign inversion of magneto-optical effects (Faraday rotation and magnetic circular dichroism) observed in films that were deposited on the GGG substrate pre-treated by 1 keV and 4 keV Ar⁺ ion beams is a result of the substrate surface amorphization caused by the ion bombardment.
