The temperature dependence of the magnetisation of Er2-xYxFe14B compou
nds was analysed using a simple two sublattice molecular field theory.
The molecular held coefficients n(FF) n(RR), n(RF), were obtained and
the theoretically calculated Curie temperatures were found to agree w
ell with the experimental values. (C) 1998 Elsevier Science B.V. All r
