Robust magnetic order of Ce 4f-electrons coexisting with superconductivity in CeFeAsO${}_{1-x}$F${}_x$

T. Shang, L. Jiao, J. Dai +4

The electrical resistance of CeFeAsO${}_{1-x}$F${}_x$ (x = 0.06 and 0.08) has been measured in a magnetic field up to 40T. At zero field, the sample with x = 0.06 shows a structural ph…
