摘要: The enhancement of the superconducting transition temperature by pressure was studied up to ~1.5 GPa for samples (La1-xSrx)2CuO4 with varying strontium content x. Simultaneously measured Hall coefficients were found be independent in present range, ruling out a induced carrier density change as an origin Tc enhancement. coefficient roughly same two regimes. i.e. x<0.08, where increases and 0.08
