✦ Synopsis

Single crystals of antiferromagnetic La2CuO4+ b (TN=250K) which show superconductivity ( Tc=32K ) with the Mcissner fraction of 9.1% were grown from a melt with excess of CuO. The electrical resistivity and the Hall effect have been measured on the as-grown and heat-treated samples under high magnetic fields up to 10 1". The anisotropic superconducting properties are similar to the other high T c superconductors. A scattering mechanism of the carriers in the normal state is discussed based on a single carrier model.
