Crystal structure, magnetic and optical properties of thin films, synthesized on base of SmCo5 and Nd2Fe14B powders
- 1 Laboratory of Phys. of Magnetic Materials – Scientific-Practical Materials Research Centre NAS, Minsk, Belarus
Thin Sm-Co and Nd-Fe-B layers with a thickness of ~ 30 – 850 nm were synthesized by thermal evaporation method using permanent magnets SmCo5 and Nd2Fe14B powders as precursors on glass substrates. The crystal structure was studied by X-ray diffraction in CuKa – radiation at room temperatures. It was shown that thin films are characterized by a highly amorphized crystalline state. It was found that annealing of the films leads to the destruction of the compositions on the glass substrate. In the temperature range of 80 – 1100 K using the ponderomotive method the specific magnetization in the “heating – cooling” mode was measured. Magnetic hysteresis loops were studied in the temperature range of 5 – 300 K. In the wavelength range of 250 – 3000 nm, optical transmission spectra of transparent Sm-Co and Nd-Fe-B films with a thickness of ~ 30 nm were studied.
