Temperature dependence of saturation magnetization and magnetization process of a field oriented sample in a pulsed field up to 13T at several temperatures are measured for GdCo4B. The following main conclusions have been obtained: (1) the Curie temperature and the compensation point are 517 K and 421 K, respectively, (2) the averaged Co-moment is 1.04 μB, suggesting the 6i-Co has about a half of that of the 2c-site Co, (3) the exchange parameter between Gd and Co spins, JGd-Co/k, is estimated to be 8.5 K from the temperature dependence of Gd-sublattice magnetization, (4) Gd-sublattice anisotropy constants have been estimated as follows; 5.8×106 erg/c.c. at T=78 K, 3.9×106 erg/c.c. at T=147 K and 2.9×106 erg/c.c. at T=225 K, which are well explained by Gd–Gd and Gd–Co dipole–dipole interactions, and (5) the anisotropic saturation moment has been observed and can be attributed to anisotropic Co moment.
