Ultrasonic measurements on a high-To superconductive CaLaBaCu3OT\_y polycrystalline sample have been performed. Both the transverse and longitudinal sound velocities in the sample show an anomaly around To. The Young's Modulus, Debye temperature, Bulk modulus and Poisson's ratio were calculated; the
Magnetization measurements on a polycrystal of CaLaBaCu 3 O 7Àd 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
