Amorphous films of yttrium bismuth ferrite garnet were obtained by thermal evaporation. Morphological and elemental analysis was carried out using an electron microscope. The IR spectra of the precursors and the amorphous film were measured. Measurements of theI-U characteristics were carried out in different electric fields and in the temperature range of 80-450K. The hysteresis of the I-U characteristic and the difference between high-resistance and low-resistance resistance by an order of magnitude at voltages of hundreds of microvolts were found.
