The corrosion action for bulk and thin Nd₂Fe₁₄B films magnets in different corrosion media was studied. The thin Nd-Fe-B films of 100 nm ≤ d ≤ 1000 nm were deposited on glass substrate by "flash" evaporation method. The structure and microstructure of the samples were studied by X-ray diffraction analysis, scanning electron microscopy. The temperature dependence of the magnetization before and after corrosion action was carried out by ponderomotive method in the temperature range 80 ≤ T ≤ 800 K. It is shown that the specific magnetizations of the thin Nd-Fe-B films with d ≥ 1000 nm are comparable to those measured for the powder samples. The values of the coercive and saturation fields were determined from the hysteresis loops measurements.
