Abstract
The enhancement of the superconducting transition temperature by pressure was studied up to ∼1.5 GPa for samples of (La1-xSrx)2CuO4with varying strontium contentx. Simultaneously measured Hall coefficients were found to be independent of pressure in the present range, ruling out a pressure induced carrier density change as an origin of theTcenhancement. The pressure coefficient ofTcwas found roughly the same for the two regimes. i.e. forx<0.08, whereTcincreases withx. and for 0.08<x<0.15 where it decreases withx. These results are discussed in the context of the current controversy over the nature of the electronic state in this class of materials.
