Temperature-dependent photoemission spectral weight transfer and chemical potential shift in Pr${}_{1-x}$Ca${}_x$MnO${}_3$ : Implications for charge density modulation

K. Ebata, M. Hashimoto, K. Tanaka +3

We have studied the temperature dependence of the photoemission spectra of Pr${}_{1-x}$Ca${}_x$MnO${}_3$ (PCMO) with $x=0.25$, 0.3 and 0.5. For $x=0.3$ and 0.5, we observed a gap in the…
