| Summary: | In this work, planar symmetric (Dot) and non-symmetric (Nanowire) structures were combined to fabricate the modulated planar structures (Dumbbell) of Ni80Fe20. Four set of samples were fabricated on top of the signal line of coplanar waveguides with dumbbell’s axis along and perpendicular to it using methods of photolithography, electron beam lithography and liftoff. The diameter of the dots was varied to study the effect on both static and dynamic properties of modulated structures. The static magnetization reversal was investigated by NanoMOKE measurements, whereas broadband ferromagnetic resonance spectroscopy was carried out to probe the dynamic properties in GHz range. Micromagnetic simulations were performed to comprehend the experimental results in detail. |
