The electrical resistance of SrxLa2-xCuO4-y has been measured under magnetic fields up to 21.1 T between 4.2 and 50 K. The onset of Tc was 41.0 K in H=0 and 33.0 K in H=21.1 T. H2c(0) is estimated to be 76 T according to the dirty limit theory of type II superconductivity. The Hc2 value is near the Pauli limit value and is higher than that (60 T) of PbMo6S8. SrxLa2-xCuO4-y is one of the highest-Hc2 superconductor as well as a high-Tc one.
