Magnetization measurements on a polycrystal of CaLaBaCu 3 O 7Γd in high magnetic fields (20 to 50 kOe) are reported. The sample has a zero-field transition temperature T c0 77 K and a transition width of 2.0 K. The results show large fluctuation effects, which can be explained by Ginzburg-Landau flu
