INDUCING IN-PLANE MAGNETIC ANISOTROPY IN SPIN-SPRAYED Ni-Zn-Co FERRITE FILMS EXHIBITING STRONG MAGNETIC LOSS AT GHz RANGE

摘要

We report in this paper that a definite in-plane magnetic anisotropy is induced in the spin-sprayed Ni-Zn-Co ferrite films by applying external magnetic field during deposition. This anisotropy causes a large magnetic absorption in GHz range, advantageous for applying to conduction noise suppressors.
