摘要：

The reflectance of EuO from above the Curie point at 69°K down to 1.5°K shows splittings in the two main peaks near 1.5 and 4.7 eV. The first peak is a polarization-dependent triplet at 1.5°K and a doublet at 70°K. The data suggest that the 1.5-eV peak is associated with the absorption edge and arises from the transition 4f7(S728)→4f6(FJ7)5d(t2g). The narrow t2g sub-band is exchange split by 0.25 eV at low temperatures. © 1969 The American Physical Society.
