摘要
Spectra from photoemission spectroscopy (PES) of a recently discovered layered-perovskite superconductor Sr2RuO4 are reported. The PES spectrum of Sr2RuO4 around the Fermi level (E-F) is apparently different from the non-interacting density of states obtained by a band calculation, suggesting the importance of strong electron correlation in this system.
