The endothermic peaks around 950 degrees C are structured for some compositions. Most of the samples which are heat treated according to their own DTA/TGA results showed anomalous resistive transitions between 125 K and 260 K. XRD, SEM-EDAX and FTIR investigations reveal that the samples are multiphase. At least one of the IR absorption bands at 401, 405, 489 and 543 cm(-1) were observed in the spectra of the samples showing anomalous resistive transitions.eninfo:eu-repo/semantics/closedAccess[No Keywords]Conference Object23587988010.1016/0921-4534(94)91664-02-s2.0-26344448625Q2WOS:A1994QC69400079N/A
