5. Structure and Dynamics in Transition Metal Perovskites — An Optical Spectroscopy Study
Sammanfattning : Transition metal oxides with the perovskite structure exhibit a vast number of exotic properties due to the large number of competing degrees of freedom at the Fermi surface. Together with couplings between and correlations within these degrees of freedom, this class of materials is of high interest from both a practical and theoretical point of view. LÄS MER
