Abstract
A phenomenological approach to the theory of the isotope effect in fer romagnets is developed on the basis of the phenomenon of magnetoelasti city. Parameters whose experimental measurement permits a quantitative calculation of the contribution of acoustic phonons to the isotope sh ift of the Curie temperature are identified. An estimate of the isotop e shift of the Curie temperature in the Invar alloy Fe0.75Pt0.25 is gi ven. (C) 1997 American Institute of Physics.
