Effects of pressure on the Curie temperature and the magnetization of itinerant-electron ferromagnetic compounds Lu (Co<SUB>1-x</SUB>Ga<SUB>x</SUB>) <SUB>2</SUB> have been investigated in the concentration range from x = 0. 10 to 0. 20. All of the compounds show large negative values of ∂T<SUB>c</SUB>/∂P and ∂M<SUB>s</SUB>/∂P. An anomalously large negative ∂T<SUB>c</SUB>/∂P was observed around x = 0. 10, being the critical concentration of the onset of ferromagnetism. This phenomenon can be explained qualitatively by taking spin fluctuations into account. The spontaneous magnetization begins to decrease drastically above a certain pressure, suggesting the onset of the metamagnetic transition from the ferromagnetic to paramagnrtic state.
