Abstract
Ce2Fe17-xMnx compounds with x = 0-2 were synthesized and their magnetizatio ns were measured on polycrystalline samples at temperatures of 4.2-300 K in magnetic fields of up to 20 kOe. The binary Ce2Fe17 alloy was established to exist in low-temperature ferromagnetic and high-temperature helical anti ferromagnetic ordered states; with substituting manganese for iron, the Nee l temperature of the Ce2Fe17-xMnx alloys decreases monotonically, whereas t he temperature of the ferromagnetic-antiferrornagnetic transformation chang es nonmonotonically and tends to zero for compositions with x = 0.5-1. The magnetization process in the Ce2Fe17-xMnx alloys with x = 0.5-1 has a metam agnetic nature.
