Description
We have found that YbNi4Cu does not order magnetically down to 4K. At temperatures over 100K the magnetic susceptibility follows a Curie-Weiss law with the parameters θp=-113K and μeff=4.8μB/f.u. This effective magnetic moment is close to the value expected for the 4f13 configuration (4.54μB). The XPS valence band spectrum is compared with the results of ab initio calculations using the SPR-KKR-CPA method, where Yb(4f) states are treated as the semi-core states. The valence band is dominated by the Ni(3d) and Cu(3d) peaks. The X-ray photoemission spectroscopy corroborates that Yb is mainly in the trivalent state in the YbNi4Cu compound
