摘要:Patterned Ni80Fe20 permalloy films with strip length of 5 mm, strip distance of 40 mu m and various ferromagnetic (FM) strip widths from 20 to 40 mu m were prepared by pulse laser deposition and photolithography for study the microwave performance of permalloy films. Comparing with the continuous magnetically isotropic permalloy film, the anisotropy fields H-K increase with the decrease of the FM strips' width. As a result, the ferromagnetic resonance frequency f(r) is enhanced from 1.71 GHz of continuous film to 2.1 GHz of patterned film with FM strip width of 20 mu m. The comparison between f(r) and H-K demonstrates that the enhancement of f(r) can be attributed to the increase of H-K due to the shape anisotropy of permalloy strips. (C) 2016 Author(s).
