 Abstract: Scanning tunneling microscopy and spectroscopy were conducted over a broad temperature range on single crystals of Pr0.68Pb0.32MnO3. Spectroscopic studies revealed inhomogeneous maps of the zero-bias conductance with a broad distribution of the local conductivities only within a narrow temperature range close to the metal-insulator transition. An analysis of the conductance histograms based on these maps gave direct evidence for phase separation into insulating and conducting areas. This phase separation was found to be confined only to the transition region. Copyright (C) EPLA, 2008.
