A comparative study of the YBa 2Cu 3O x and Y 2Ba 3Cu 5O y superconductors: Structural, electrical and mechanical properties
Abstract
Measurements of the Seebeck coefficients of the two commonly studied superconducting compositions YBa 2Cu 3O x and Y 2Ba 3Cu 5O y show that the value for the former compound is always significantly greater than that for the latter. Structural studies show a slight change in the lattice parameters of the orthorhombic structure which is common to both. Damping loss and elastic modulus observations in the compound show a significant change near the 240 K as well as at the superconducting transition.
