摘要	For the nanocomposite magnets (Nd0.9Dy0.1)(Fe0.77Co0.12Nb0.03B0.08)(5.5)/alpha-Fe, the best magnetic properties were obtained with the average grain size of alpha-Fe d = 15 nm and with the content of alpha-Fe c(m) = 45 wt % that is well below the structural percolation threshold of the soft magnetic phase. The measured dependence of the coercivity on the grain size of alpha-Fe tends to indicate that the optimum grain size d(op) increases with increasing alpha-Fe content, for c(m)>30 wt %. If d>d(op), contracted hysteresis is formed; if d
