Abstract

Electrical resistivity measurements on the superconducting oxides of the compositions Y0.9−x Pr x Ca0.1Ba2[Cu1−y Zn y ]3O7−δ (0≤x≤0.20 and 0.0≤y≤0.10) sintered in oxygen atmosphere were carried out to obtain the normal and anomalous pseudogaps in underdoped and overdoped samples. It is observed that pseudogap temperature T * decreases with increasing doping level p in the underdoped case. For the overdoped sample with y=0.06, T * shows no p dependence.
