摘要：

We have studied the temperature dependence of the magnetization and its field-dependence (up to 35 T) at 4.2 K in several series of compounds of the type R1-xLuxFe4B (R = Ho, Er, Tm). The magnetic isotherms at 4.2 K as well as the temperature dependence of the magnetization were analysed with a mean field model. The magnetic coupling constant JRFe in the Hamiltonian H = - ΣFe 2JRFeSR · SFe was found from both types of measurements to be equivalent to about -10.5 K. © 1990.
