Abstract
The dissertation focuses on the broadband characterization of magnetization dynamics of submicron (200-550 nm wide, 10 µm long, 100 nm thick) and micron (2-10 µm wide, 100 µm long, 100 nm thick) size patterned ferromagnetic material (Permalloy, Py) with low frequency and microwave measurement methods. Particularly the ferromagnetic resonance (FMR), damping process, magnetization reversal, mag-noise, and 1/f noise in different pattern geometry, DC current and external magnetic field bias situations are investigated. In addition to simple microwave transmission line measurements, a sensitive on-chip microwave interferometer is proposed and fabricated by means of nano-fabrication techniques. The FMR properties of an individual nanoscale Py pattern were measure with the interferometer.
