• Magnetic measurements on the single crystal RGa intermetallic compounds(R=Pr, Nd, Sm, Tb, Dy, Ho and Er) have been carried out in the 4.2 K to 350 Ktemperature range. All the compounds, except ErGa, are ferromagnetism withhigh coercive force along the easy direction. ErGa compound is antiferromagnet-ism. The magnetization curves for the heavy rare earth compounds were fairlywell explained on the basis of the molecular field model, including the crystalfield. But, for light rare earth compounds, the agreements between the expert-mental and the calculated values were not so good. Crystal field parameters B') andB", were determined from the anisotropy of paramagnetic Curie temperatures onthe basis of the molecular field theory. These parameters were compared wjththose of the point charge model.
