摘要：

Go/Bi2Sr2CaCu2Ox (BSCCO) and Au/BSCCO tunnel junctions have been fabricated in order to study effects of the spin injection into the superconductors. The junction with 100 x 100 mum(2) was fabricated on the cleaved BSCCO single crystal. In both cases, gap structures were clearly observed in dl/dV spectra. The gal, energy of Co/BSCCO junction (28 mV) was smaller than that of Au/BSCCO junction. The zero-bias conductance peak (ZBCP) was observed clearly for the Au/BSCCO junction. It is considered that these differences between Co and Au junctions are due to the spin-polarization in the current flowing through the junctions.
