My master thesis was supervised by PD Dr. Jan Minar (AK Prof. H. Ebert, LMU Mümchen). The focus was on comprehensive theoretical study of novel class of materials as hot candidates in field of spintronics. All ab-initio calculations were based on the multiple scattering approach (Korringa-Kohn-Rostoker (KKR) method) and density functional theory.

Photochromic compounds are a class of molecules, which molecular structure can be changed upon irradiation of optical or electrical stimulation. In the case of diarylethenes (DAEs), the cyclization reaction - bond formation at the photochromic core can be induced by UV light, while the cycloreversion reaction - bond cleavage can be initiated by visible light. One of the various reasons why this family of materials has attracted so much attention is the combination of an outstanding performance, good thermal stability and most effective optical properties with possible applications in optoelectronics, molecular sensors and memory storages. We focus on a comprehensive study of the ultrafast switching processes in the broad spectral and time ranges for series of DAEs with optimized structure.
