Abstract

Recent results of experimental studies on high-Tc oxide superconductors are presented. Anisotropy and temperature dependence of the magnetic susceptibility χ of La2CuO4 do not seem to be easily explained by a simple antiferromagnetic spin ordering with the spin direction within the CuO layers. Moreover with increasing magnetic field perpendicular to the layers, χ exhibits a sudden increase below TN. The tunneling study revealed that the energy gap value of YBa2Cu3Oy is consistent with BCS theory and any additional structure has not been observed in the present tunneling spectra.
