Abstract
Using x-ray-photoelectron spectroscopy and bremsstrahlung-isochromat spectroscopy (BIS), we have studied the UxY1−xB4 system which shows a magnetic-nonmagnetic transition at x=0.6. Contrary to the conclusions from previous magnetic measurements, we find that the U 5f exhibit itinerant nature for all values of x primarily via hybridization with B s, p states. Evidence of increasing correlation effects with decreasing x is found in the BIS spectra. This is suggested to be responsible for the observed magnetic property.
