Crystalline and magnetooptical characteristics of (Tb,Bi)^sub 3^(Fe,Ga)^sub 5^O^sub 12^ deposited on (Y,Nd)^sub 3^Al^sub 5^O^sub 12

Crystalline and magnetooptical characteristics of (Tb,Bi)^sub 3^(Fe,Ga)^sub 5^O^sub 12^ deposited on (Y,Nd)^sub 3^Al^sub 5^O^sub 12

We prepared Bi- and Ga-substituted Tb3Fe5O12 (BiGa:TIG) films on a Nd-substituted Y3Al5O12 (Nd:YAG) single crystal substrate by pulsed laser deposition, and investigated their magnetic, optical, and magnetooptical properties. A BiGa:TIG film deposited with a substrate temperature of 700 °C shows the...

Zusammenfassung:We prepared Bi- and Ga-substituted Tb3Fe5O12 (BiGa:TIG) films on a Nd-substituted Y3Al5O12 (Nd:YAG) single crystal substrate by pulsed laser deposition, and investigated their magnetic, optical, and magnetooptical properties. A BiGa:TIG film deposited with a substrate temperature of 700 °C shows the easy axis of magnetization along the out-of-plane direction of the film and the Faraday rotation angle of 900°/cm at a wavelength of 1064 nm. The epitaxial growth of the film is confirmed by X-ray diffraction analysis.
