Zusammenfassung:The effect of the alloying element Cr on the structure, parameters of hyperfine interactions, and magnetic properties of the nanocomposites of compositions [([Fe.sub.1-x][Cr.sup.x]).sub.75][C.sub.25], where x = 0.01- 0.10, which was obtained by mechanical synthesis with subsequent annealing, has been investigated. It has been established that alloying with chromium reduces the coercive force, saturation magnetization, and Curie temperature of cementite. At the same time, alloying with chromium increases the thermal stability of cementite.
