TEM image of nickel nanowire (sample Ni1) extracted from the alumina template.
Coplanar wave guide (CPW) transmission line fabricated on top of the alumina template filled with Ni nanowires.
Angular variation of the FMR field positions measured at . corresponds to the applied magnetic field parallel to the wire axis and corresponds to the perpendicular configuration. The symbols are experimental data and the solid lines were obtained using Eq. (1).
Angular variation of the FMR linewidths measured at for sample Ni4 which is for NW of length. The dashed line is a guide to the eyes.
Transmission response measured by using a network analyzer system on the CPW based NW substrate. The top level shows two transmission spectra of sample Ni4 at two different magnetic fields. Bottom panel shows the notch frequencies vs dc magnetic field, , applied perpendicular to nanowires for samples Ni3 (solid circle) and Ni4 (open circle). The solid lines correspond to the theoretical fit using Eq. (4).
