Imaging magnetic excitations in confined magnetic structures.
Journal of Physics D: Applied Physics 41 (16), p. 164010.
In this paper we revisit some particular aspects concerning the dynamic magnetization of thin Ni80Fe20 discs. In particular we address details of the excitation spectrum of Ni80Fe20 discs subjected to in-plane magnetic cw microwave fields. In this case imaging the dynamic magnetization allows us to estimate the internal magnetic field of the ferromagnetic element.
