Scope:

3d electrons in transition metal oxides and π electrons in organic complexes often show interesting electric and/or magnetic properties. Those are called strongly correlated electron phenomena and have widely been studied so far. Among them, the valence transition in materials (so called valence skipping phenomena) is one of the important and intriguing research themes. In this symposium, we focus on three topics (the spin-crossover effect, electronic ferroelectrics, and ultrafast optical functions) concerning the valence skipping effect which have intensively been investigated especially in our country, and discuss recent theoretical and experimental progresses of the interesting valence transition phenomena.

Topics:

1. Novel electric and magnetic properties with valence skipping
2. Spin crossover phenomena
3. Ferroelectic properties with valence skipping
4. Ultrafast dynamics driven by valence skipping
