Property Study of TbFeCo for All Optical Magnetic Recording

Thin films properties of amorphous TbFeCo were studied to determine its suitability for use in all optical magnetic recording. Ellipsometric techniques have been used to determine the optical properties of the films in the wavelength range of 350 to 800 nm. The effects of film thickness, Ar flow rate and presence of Ag under layer on magnetic properties were also investigated.
