Abstract
The crystal structure and physical properties for (Y,Ce compound are reported using Rietveld-refinement of x-ray powder-diffraction data, dc magnetic susceptibility, Mössbauer, and Raman spectroscopy measurements. Mössbauer data can be analyzed with three components. Component A is attributed to (S=5/2) ions in the Cu(2) site. Component B is attributed to (S=3/2) ions in the Cu(1) plane and appears only in the oxygen saturated sample. For the reduced sample, component B transforms to component , which has a lower oxygen coordination number with respect to that of component B. The Raman lines are assigned to definite atomic vibrations in close comparison with other compounds of similar structure.
