Popis: Mossbauer studies of multiple substitutions in YBCO with general formula (Y1−Z Ca Z )Ba2(Cu1−X−Y Fe Y M X )3O7−δ are reported. XRD has been used to find out the lattice parameters. All the samples show a single tetragonal phase formation. Iodometric titration is done to estimate the oxygen content. The present study discusses the effect of multiple substitutions of 3d-ions like Ni, Zn, Co, Mn, Cr in YBCO and the effect of various substitutions on charge balancing, oxygen content and site occupancy.
