Abstract

We present X-ray and magnetization results for the compound [Y_0.75Ca_0.25]SrBaCu_3-x (PO₄)_xO_y with 0.0 ≤ x ≤ 0.30 synthesized at normal pressure and temperature. X-ray diffraction patterns show that for x = 0.0 the compound crystallizes into an orthorhombic phase. For increasing x a tetragonal phase is obtained. The Rietveld method was used to refine lattice constants. The magnetization measurements show that the samples were all superconductors over a range of temperatures from 10 to 100 K. The diamagnetic transition temperature T_c decreases with increasing (PO₄)^3- concentration (T_c = 55 K for x = 0.0 and T_c = 35 K for x = 0.30).
