For binary and multicomponent amorphous ferromagnetics based on metals of the iron group and produced by fast quenching from melt, calculations of correlation-field intensity Нl, Bloch constant B, factor of spin-wave rigidity Д, constant of exchange interaction ?, and correlation radius rc are carried out within the stochastic magnetic-structure approximation. Regularities in changes of local magnetic parameters are determined depending on chemical composition of amorphous ferromagnetics and at their transition in crystal state. Reasons for existence of correlations between the exchange interaction and the heterogeneities of magnetization in nanocrystalline 3d-ferromagnetics are analyzed.
