THE LINEAR TEMPERATURE BEHAVIOR OF RESISTIVITY AND OXYGEN STOICHIOMETRY IN YBa_(2)Cu_(3)O_(7-x)

         

摘要

By employing a gettered annealing technique,we studied the relationship between the resistivity p(x,T)(20℃≤T≤300℃)and oxygen content»n the high-Tc superconductor YBa_(2)Cu_(3)O_(7-x).ρ(x,T)is approximately linear for 0.0≤x≤0.6,and both the slope dp/dT and the residual resistivity increase continuously with decreasing oxygen content.A qualitative analysis is given.
