Abstract

Epitaxial Ce and Bi comodified iron garnet and Ce-modified yttrium iron garnet thin films were grown on (100)-oriented Gd3Ga5O12 substrates by pulsed laser deposition, in order to investigate the role of Bi3+ ions and their contribution to the structural, chemical, and magneto-optical properties. Both films showed a strong Faraday rotation of 0.65 deg/mu m and 0.52 deg/mu m at 1.55 mu m, respectively. The valence state of the Ce ions was significantly changed by the substitution with Bi3+, which in turn was demonstrated to lead to an increase in the concentration of Ce3+ as well as to the decrease in the lattice mismatch.
