초록

A device for the imaging of magnetic fields and domain structures based on the Faraday effect has been developed using garnet thin films prepared by the metal-organic decomposition method as indicators. The sensitivity was improved by using high concentration bismuth substituted yttrium iron garnet thin films with in-plane magnetic anisotropy. Low temperature synthesis of the films (BixY3-xFe5O12; x - 2) on glass substrates of thickness about 0.8 mu m is described and the Faraday rotation angle is measured to be about -11 degrees/mu m.
