在选定的温度低于300K以下，测量了重费米子化合物SmFe4P12和SmOS4Sb12在Sm L 3边附近的X射线吸收光谱。光谱表明，SmFe4P12中的Sm离子在14-300K之间以三价形式存在，与温度没有明显的关系。而Smos 4Sb12在30 0K时为2.83，在15 0K以下有明显的下降，表明Sm2+离子在重费米子态中对外加磁场不敏感起着重要作用.
The X-ray absorption spectra of the heavy fermion compounds SmFe 4 P 12 and SmOs 4 Sb 12 have been measured near the Sm L 3 -edge at selected temperatures below 300 K. The spectra show the valence of Sm ions in SmFe 4 P 12 to be trivalent between 14 and 300 K with no significant temperature dependence. In contrast, that in SmOs 4 Sb 12 is 2.83 at 300 K and shows a significant decrease below 150 K, indicating an important role of the nonmagnetic Sm 2+ ions in the heavy fermion state that are insensitive to an applied magnetic field.
