Study of static and dynamic properties of planar dumbbell shaped structure of Ni80Fe20

Study of static and dynamic properties of planar dumbbell shaped structure of Ni80Fe20

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 usin...

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.
