Molecular field theory analysis of Gd2Co2Al and Gd2Co2Ga compounds

The molecular field theory based on two‐sublattice model was employed to analyse the temperature dependence of the magnetization of Gd2Co2Al and Gd2Co2Ga compounds. The molecular field coefficients nCoCo, nGdCo and nGdGd were obtained by a numerical fitting process. The theoretically calculated Curi...

Zusammenfassung:	The molecular field theory based on two‐sublattice model was employed to analyse the temperature dependence of the magnetization of Gd2Co2Al and Gd2Co2Ga compounds. The molecular field coefficients nCoCo, nGdCo and nGdGd were obtained by a numerical fitting process. The theoretically calculated Curie temperatures were found to agree well with the experimental results. The exchange fields HCo(T) and HGd(T) were presented.
