英文摘要
To investigate the possibility of superconductivity induced by orbital fluctuations, we performed nuclear-magnetic-resonance measurements on LaFeAsO1-xHx in a heavily electron-doped regime where spin fluctuations are supposed to be fairly small. We unexpectedly discovered antiferromagnetic ordering in this regime and obtained a brand-new electronic phase diagram, contrary to the commonly-believed expectation in the field of strongly electron systems.
