“…As is well known, the full width at half maximum (FWHM) reflects the crystalline quality of the studied samples. The [15], to the loss of oxygen which is known to affect the c parameter [16] and can be linked to the reduction in the local Jahn-Teller distortion of the oxygen octahedron around Cu 2+ . In cuprate oxides, the Jahn-Teller mode mainly corresponds to an orthorhombic distortion of CuO 2 square in which two Cu-O bonds are elongated and other two shortened [17].…”

The work reported in this paper aims at a better understanding of the magnetic doping effects on the structural and electrical properties for a series of YBa 2 (Cu 1−x Co x ) 3 O 7−δ ceramics. The Co doped YBa 2 Cu 3 O 7−δ are (YBCO) prepared by conventional solid state reaction method and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), differential thermal analysis (DTA) and resistivity measurements. The crystal lattice parameters are found to change due to the cobalt doping and tendency to a structure phase transition from orthorhombic to tetragonal, which is confirmed by the decrease of the degree of orthorhombicity. The morphology examination with SEM revealed gradual increases of grain size with x = 0.02 Co, a high porosity is observed in the doped samples compared to the pure one. The decomposition temperature of YBCO is pushed from temperatures above 975˚C to lower temperatures of 945˚C. The resistivity measurements of doped samples with x = 0.04 and 0.06; shows a deviation in from T-linear behavior due to the opening of a pseudogap.
