ABSTRAKT
The array of Ni0.8Fe0.2 (permalloy) nanowires deposited in the alumina nanopores of the aluminum substrate has been studied by the ferromagnetic resonance technique in 30-40 GHz frequency range at T=300 K and in 70-80 GHz frequency range at T= 4.2 K. The dependences of magnetic resonance response on frequency, on wire orientation and on temperature have been measured. The well-known Smith-Beljers equation has been applied for the analysis of the ferromagnetic resonance. The values of gyromagnetic ratio and anisotropy field have been estimated. The results of investigation can be used to design electronic microwave devises with temperature controlled magnetic properties.
