Mechanical against chemical pressure in the Y(Ba1-xSrx)(2)Cu3O7-d system
The structural refinement of YSr2Cu3O6.84 allows us to analyze why the chemical pressure applied to YBa2Cu3O6.84, by substituting Sr for Ba, results in a decrease of Tc (88 to 63 K). Even though the chemical pressure induces a volume decrease of 5.7%, the thickness along the c axis of the supercondu...
