摘要:

We used photoemission spectroscopy with synchrotron radiation to search for evidence of a resonating valence bond (RVB) state in a series of thallium‐containing high‐temperature superconductors. As in the case of Bi compounds, no positive evidence was found, and the data imply a low upper limit for the energy of hypothetical spinons.
