Аннотация:The effect of interstitial nitrogen and hydrogen atoms on the structural and magnetic properties of LaCo11Al2 and CeNi8.5Si4.5 was studied. Synthesis of LaCo 11Al2H3 and LaCo11Al2N2.5 was performed under a pressure of 30 bar hydrogen and nitrogen and at the temperatures 623 and 773 K. Synthesis of CeNi 8.5Si4.5H0.9 and CeNi8.5Si 4.5N0.5 was realized under a pressure of 30 bar hydrogen and nitrogen at the temperatures 723 and 923 K. Magnetic measurements were made for randomly oriented and aligned samples in the temperature range 4.2-750 K and at magnetic fields up to 140 kOe. The saturation magnetization of LaCo 13 is decreased by a partial substitution of the transition metal in the 3d sublattice by Al and further reduced by hydrogenation of LaCo11Al2.
