The martensitic transition temperature T M and the Curie temperature T C of the ferromagnetic alloys Ni2Mn1-xCuxGa (0 ≤ x ≤ 0.40) were measured under pressure. We estimated the pressure derivatives dT M/dp and dT C/dp from the results. The values of dT M/dp and dT C/dp for Ni2MnGa (x = 0) were -4.5 K/GPa and +3.9 K/GPa, respectively. The values of dT M/dp increased from negative to positive with increasing x in Ni2Mn1-xCuxGa. The values of dT C/dp approached zero with increasing x.
