Abstract

Single phase samples of PrBa2Cu3O7-δ with orthorhombic structure were prepared by solid State reaction method. Resistance measurement was performed by a standard dc four-probe technique. It is found that the resistance exhibits semiconductor-like behavior. Results of XPS measurement indicate obviously the existence of Pr4+ in PrBa2Cu3O7-δ. Finally, the band structure was used to discuss the reasor why PrBa2Cu3O7-δ does not show superconductivity.
