Abstract
The crystal structure and superconducting properties of samples of YBa2Cu3O7-x with oxygen contents 0.21 ≤ x ≥ 0.67 were investigated. The crystal structure and magnetic properties change with oxygen content. All samples were found to have orthorhombic crystal structure. The lattice parameters a and c were observed to monotonically increase while b nearly monotonically decreases with decreasing oxygen content. The unit cell volume increases with decreasing oxygen content as well. The critical temperature, Tc, and the superconducting volume fraction of the samples decreased with decreasing oxygen content
