Mössbauer effect studied in rare-earth oxides (REu)O3 (R = Pr, Nd, Sm)

Abstract Both X-ray diffraction and the Mossbauer effect have been used to study the double rare-earth oxide solid solutions (REu)O3 (R = Pr, Nd, Sm), which were synthesized with a combination of high pressure and high temperature for the first time. It is shown that all products are of the B-type (monoclinic) structures of single phase. The hyperfine interactions depend strongly on the ligand volume of Eu ions.
