Effect of Pressure on the Hall Effect, Electrical Resistivity and Magnetoresistance in the High-T_cSuperconductor, YBa₂Cu₃O_7-δ

Abstract

The pressure effect on the Hall effect, electrical resistivity and magnetoresistance ( T < T c ) has been measured in sintered YBCO. Under pressure, the Hall coefficient decreases above T c . The size of the negative peak of the Hall effect just below T c also decreases while T c increases. Under pressure, the magnetoresistance increases ( T <86.6 K) and decreases (86.6< T <89.8 K).
