    • Abstract


      We have investigated the variation of transition-temperature and coupling parameter with the composition concentration in La2 −x(Ba, Sr)xCuO4 superconductors using a formulation developed on the basis of an idea of pairing of charge carriers by exchange of both acoustic plasmons and phonons. Reasonably good agreement is found between the recent experimental results and our theoretical results on the superconducting transition temperature.
