Аннотация:The films studied are fabricated by LB vertical lift from the water solution of Gd acetate, as the Gd ions are adsorbed on the stearic acid LB monolayer created on the water subphase surface. The chemical analysis shows that the structural unit of the LB films consists of the patterns reveal almost perfect periodic layered structure of LB films studied. For the spectroscopic magnetization induced second harmonic generation studies the output of a femtosecond Ti:sapphire laser is used with the wavelength tuning range from 700 to 800 nm.
