151Eu Moessbauer effect in light rare-earth oxides
- 1. Group of Solid State Physics, Jilin University, Changchun, People's Republic of China (China)
Description
The double-rare-earth oxides LaEuO3, PrEuO3, NdEuO3, and SmEuO3 were synthesized by a high-pressure and high-temperature method. The analyses of x-ray diffraction show that LaEuO3 is of A-type (hexagonal) structure, and that PrEuO3, NdEuO3, and SmEuO3 are of B-type (monoclinic) structure, and CeEuO/sub 3.5/ is of F-type (fluorite) structure. Moessbauer spectra were measured using the 21.6 keV γ ray of 151Eu at room temperature. It has been observed that the hyperfine interactions depend strongly on the volume of Eu ions. This volume effect of the isomer shift can be mainly attributed to the distortion of the 5s shell of Eu ions
