Abstract
We use a spatially resolved, direct spectroscopic probe for electronic structure with an additional unique sensitivity to chemical compositions to investigate high quality single crystal samples of La¼ Pr3/8Ca3/8MnO3, establishing the formation of distinct insulating domains embedded in the metallic host at low temperatures. These domains are found to be at least an order of magnitude larger in size compared to previous estimates and exhibits memory effects on temperature cycling in absence of any perceptible chemical inhomogeneity, suggesting long-range strains as probable origin.
