Outline of Final Research Achievements |
We have studied novel physical properties that emerge when the local degrees of freedom of valences derived from the valence skip phenomenon are hybridized with conduction electron systems. An anomalous increase in the nuclear magnetic relaxation rate was observed at low temperatures in the case of Tl-doped PbTe, which is most promising candidate that may skip valences. As a result of comparative verification with the case of various dopants, it was found that anomalies in the electronic state are observed only when the dopant is Tl. It suggests this phenomena is very rare. We plan to continue to research anomalous materials with physical properties that are emerged when the fluctuation of the local degree of freedom of electrons.
