Abstract
We have studied the Mn 2p, Ca 2p, and Pr 4d core levels of Pr1–xCaxMnO3 (x = 0.2, 0.33, 0.4 and 0.84) as a function of x using X-ray photoelectron spectroscopy both at room temperature as well as 77 K. Suppression of chemical potential shifts have been observed at 77 K compared to that of room temperature spectra. We have discussed this result by considering the concept of phase separation.
