초록

We discuss the preparation procedure for the fabrication of magneto-optical, bismuth-doped, yttrium-iron-garnet (Bi<inf>2</inf>Y<inf>1</inf>Fe<inf>5</inf>O<inf>12</inf>: Bi-YIG) thin films on glass substrates by using a metal-organic decomposition technique. Detailed fabrication conditions for the films with about a 11° /μm Faraday rotation angle are presented. The X-ray diffraction spectra indicate that the samples were polycrystalline. The thickness of the films were about 0.8 μm. The high Faraday rotation angle, the low optical absorption and the in-plane magnetic anisotropy of the Bi-YIG films makes them great candidates to be used as indicators for magneto-optical visualization systems. Using these indicator films, we imaged the magnetic domains in magnetic materials. © 2014, Korean Physical Society. All rights reserved.
