چکیده انگلیسی
Evolution of magnetic properties of thin FeCoB films sandwiched between two Mo layers has been studied as a function of thermal annealing at different temperatures. The as-deposited film exhibits a uniaxial magnetic anisotropy. With thermal annealing up to 300 °C, anisotropy gradually decreases while coercivity exhibits a significant increase. Uniaxial anisotropy reappears after annealing at 400 °C. In order to understand the origin of magnetic anisotropy in the film, in-plane and out-plane X-ray diffraction measurements have been done using Hard X-ray beamline BL-11 of INDUS-2. It is found that with thermal annealing the film exhibits significant changes in grain texture as well as internal stresses. Variation in grain texture in the film is expected to be the main cause for observed magnetic anisotropy.
