摘要：

For a composite consisting of magnetostrictive particles dispersed in a nonmagnetostrictive matrix, a simple, approximate model for the effective magnetostriction, defined as the ratio of the magnetostriction of the composite to that of the magnetostrictive component, is described. The predictions of the model;compare well with measurements on SmFe2-based composites having Al and Fe matrices. (C) 1997 American Institute of Physics.
