The electrical resistance R of single-phase, sintered YBa2Cu3O7−δ has been studied as a function of pressure p and temperature T in the range 300 to 500 K and 0 to 1.5 GPa (15 kbar). R is linear in T and has an initial pressure coefficient of about −13 %/GPa. The pressure dependence of Tc has also been measured up to 1 GPa, with the result dTc/dp = 0.45 K/GPa. The results are discussed in terms of electron-electron scattering, electron-phonom scattering, and the resonating valence bond theory, but none of these can fully explain the results.
