Various optical luminescence spectroscopic techniques were used to characterize the high T<sub>c</sub>superconductor YBa<sub>2</sub>Cu<sub>3</sub>O<sub>x</sub>.
The chemical state of grain boundary cosegregation of Ce and P in Fe-P-Ce alloy system was studied bymeans of Auger Electron Spectroscopy(AES).The Auger peaks o
It is well known that for technological application,a great effort has been done to enchance J_c value ofsuperconducting YBaCuO sintered bulk.Except oxygen cont
The structure of the La-LaCl<sub>3</sub>-KCl molten system at 1223K has been investigated by computersimulation using Monte Carlo method.The partial radial dist
