摘要
The temperature dependence of the magnetisation of Er2-xYxFe14B compounds 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 well with the experimental values.
