Ytterbium high pressure studies

In another paper Paparoditis et Suryanarayanan (1972) have reported the magneto-optical properties of thin films codeposited on heated substrates (67(1-770 K). They have shown that the properties depend especially on the Se concentration. Suryanarayanan et al. (1974) have studied YbTe films in more detail by optical absorption and magnetic circular dichroism. They proposed an energy level diagram, and concluded that the f-levels of ytterbium are located between the valence and conduction bands. These optical properties can be linked to a S.C.-M.-type transition, like the one observed at high pressures (150-190 kbar).
