Measurements are reported of the conductivity and the dielectric constant (ยข1) at frequencies (to) up to 20 MHz and magnetic fields up to 15 T for a single crystal of La2CuO4+y with y varied in the range 0.001 -0.01. The frequency dependence of the conductivity at low temperatures follows a power la
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 magnet
