| Abstract: | The temperature dependence of magnetization of the R3Co11B4 compounds has been analysed using the two-sublattice molecular field theory. The molecular field coefficients, nCoCo, nRCo, nRR, have been calculated by a numerical fitting process. The analytic form of the exchange field HR(T) varying with temperature for each of the R3Co11B4 compounds is presented, and some results are discussed. |
