Title: Orbital Ordering: An Introduction with Application to MNiO2 (M = Na,Li)
Speaker: Mr. Eric Mills
Institute: McMaster University – Department of Physics & Astronomy
Location: ABB 102
Description:
Transition metal oxides, by virtue of partially filled d-bands, can give rise to a rich variety of physics stemming from the spin, orbital, and charge degrees of freedom. I will explain how these degrees arise in the TM oxides, and how simple principles of quantum mechanics lead to the coupling of these degrees. I will then discuss orbital ordering, using as an example the materials NaNiO2 and LiNiO2, which also exhibit geometric frustration.
