Characterization of Magneto-optical Thin Films for Sensor Use
1989 (English)In: SPIE Proceedings Electro-Optic and Magneto-Optic Materials and Applications, vol. 1126 / [ed] Jean-Paul Castera, 1989, Vol. 1126, 77-84 p.Conference paper (Refereed)
As a part of a fibre optical sensor development project we have made an evaluation of different optical waveguiding techniques to study the properties of thin magnetooptical films. Because of the application the methods are focused on the determination of the Faraday rotation, the linear birefringence and the dynamics and anisotropy of the magnetic properties of the samples. Measurements using holographic grating, prism and edge (end-fire) light coupling to different substituted YIG films are presented. The advantages of the different methods are discussed and it is shown that the launching technique may affect the properties to be measured. Film stress caused by the prism coupling method is found to influence the magnetic anisotropy.
