“…It is possible that the difference in the nature of distortion could be one of the reasons for such stripes. These To understand the nature of phase separation in the present work, one can propose two scenarios [38,39] (a) two phases coexisting in the same grain; (b) two phases lying in two different grains. In the first scenario, it is expected that one phase grows at the cost of the other while in the second case the phase fraction remains the same.…”

In this work, we have investigated the precursor eﬀects to superconductivity in BaPb0.75Bi0.25O3 using temperature dependent resistivity, x-ray diﬀraction technique and photoemission spectroscopy. The present compound exhibits superconductivity around 11 K (TC). The synthesis procedure adopted is much simpler as compared to the procedure available in the literature. In the temperature range (10 K–25 K) i.e. above TC, our results show an increase in both the orthorhombic and tetragonal strain. The well screened features observed in Bi and Pb 4f7/2 core levels are indicative of the metallic nature of the sample. The compound exhibits ﬁnite intensity at the Fermi level at 300 K and this intensity decreases with decrease in temperature and develops into a pseudogap; the energy dependence of the spectral density of states suggests disordered metallic state. Furthermore, our band structure calculations reveal that the structural transition upon Pb doping results in the closing of the band gap at the Fermi level.closing of the band gap at the Fermi level.
