Abstract

This thesis comprises studies of 3d-5d transition metal oxides with various degrees of electronic correlation using nonlinear harmonic generation rotational anisotropy as well as time-resolved optical reflectivity methods. Specifically, we explored photo-induced phase transition in Ca₂RuO₄ and Sr₂IrO₄, discovered novel electronic phases in doped Sr₂IrO₄ and Sr₃Ir₂O₇, and investigated different types of antiferromagnetic orders in transition metal trichalcogenides MPX₃.
