Abstract

Nanoscale (30–100 nm) films of BiFeO3/BaTiO3/Ni0.5Zn0.5Fe2O4 complex composition have been obtained by the pulsed-laser deposition method. Optical properties of the films were studied in the wavelength range of 250–1000 nm. It is shown that the optical properties of amorphous films deposited at room temperature are explained by the Tauc model for amorphous semiconductors. An increase in the optical gap from 1.7 to 1.95 eV was observed with decreasing film thickness. Allowed direct-band transitions (E g = 3.1 eV) were observed after annealing of films independent of their thickness.
