Excitation of exchange spin waves using microwave nano antennas
 Davídková, Kristýna ; Holobrádek, Jakub (referee) ; Urbánek, Michal (advisor)
The transmission and processing of information could be carried out by utilizing spin waves in the future. Using the possibility of encoding information into the amplitude and wave phase would lead to the acceleration of complex mathematical operations, while for their efficiency it is necessary to work with spin waves in the exchange mode, which are characterized by a short wavelength. However, exchange mode spin waves are not so easy to generate. This bachelor thesis deals with the generation and detection of exchange spin waves, which is performed using lithographically fabricated nanoantennas on the surface of an iron-yttrium garnet magnetic layer. The bachelor thesis also contains analytical calculations of excitation spectra of the generated nanoantennas of different shapes and sizes, whose model is verified by simulations and experiment.
