Solid solutions of BiFeO3– SmCoO3were synthesized by a solid-state method. Peculiarities of the influence of isovalent substitution of Bi 3+ and Fe 3+ ions in BiFeO3by Sm 3+ , Co 3+ ions on the crystal structure and magnetic properties of Bi1–xSmxFe1–xCoxO3solid solutions are found. It is shown that the substitution 3-25% of the Bi 3+ , Fe 3+ ions in BiFe0O3by Sm 3+ , Co 3+ ions results in the gradual destruction of the antiferromagnetic and conception of ferromagnetic ordering. In this case replacing up to 10% of Sm 3+ and Co 3+ ions in SmCoO3by Bi 3+ and Fe 3+ ions leads to the stabilization of Co 3+ ions in a diamagnetic state.

The corrosion action for bulk and thin Nd2Fe14B lms magnets in dierent corrosion media was studied.The thin NdFeB lms of 100 nm ≤ d ≤ 1000 nm were deposited on glass substrate by ash evaporation method.The structure and microstructure of the samples were studied by X-ray diraction 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 specic magnetizations of the thin NdFeB lms with d ≥ 1000 nm are comparable to those measured for the powder samples.The values of the coercive and saturation elds were determined from the hysteresis loops measurements.
