Magnetic phase transitions in Y1-xGdxCo4B with x ranging from 0 to 1 have been determined in
the temperature range of 77 to 600K. The compensation temperature is found in the compounds with x?0.6,
while in the rest compounds a spin reorientation from the c-axis towards the basal plane upon decreasing
temperature is observed. On the basis of the observed Curie and compensation temperatures the
intersublattice exchange interaction coefficient has been derived and the contribution of the anisotropic
exchange interaction to the anisotropy energy of the Gd containing compounds has been estimated. ?? 1992.
