| Abstract(in English) | We have studied the electrical properties of edge junctions using PrBa_2Cu_3O_<7-x>(PBCO)-based materials having various carrier density as the barrier layers. Ca-doped PBCO(Ca_<0.5>Pr_<0.5>Ba_2Cu_3O_<7-x>,Ca-PBCO) was an overdoped version of PBCO which had Tc～20K. On the other hand, Ga-doped PBCO(PrBa_2Cu_<2.4>Ga_<0.6>O_<7-x>, PBCGO) was an underdoped version of PBCO which resistivity was higher than that of PBCO. The transport properties of junctions with PBCGO barrier layer were interpreted as tunneling via localized states. Furthermore, the IcRn products increased with decrease in the carrier density, and reached 4mV in the YBCO/PBCGO/YBCO junctions. The density of carriers or localized states in the barrier materials played an important role for the electrical properties of the junctions. |
