Preliminary measurement of the superconducting critical magnetic field Hc2 of LaMCuO system (M = Sr and Ba) with layered perovskite structure has been carried out. The results show a quite large anisotropy of Hc2 indicating that the present system has a two dimensional character of the electron transport. The measured conductivities seem to be consistent with the values estimated from the observed Hc2 by use of an ideal two dimensional band with free electron mass.
