Ferromagnetic resonance in thin films - cross-validation analysis of numerical solutions of Smit-Beljers equation. Application to GaMnAs
Piotr Tomczak, Henryk Puszkarski
(Dated: August 3, 2018) The new method of numerical analysis of experimental ferromagnetic resonance (FMR) spectra in thin films is developed and applied to (Ga,Mn)As thin films. S…
On the existence conditions of surface spin wave modes in (Ga,Mn)As thin films
H. Puszkarski, P. Tomczak
Spin-wave resonance (SWR) is a newly emerged method for studying surface magnetic anisotropy and surface spin-wave modes (SSWMs) in (Ga,Mn)As thin films. The existence of SSWMs in…
Spin-Wave Resonance Model of Surface Pinning in Ferromagnetic Semiconductor (Ga,Mn)As Thin Films
H. Puszkarski, P. Tomczak
The source of spin-wave resonance (SWR) in thin films of the ferromagnetic semiconductor (Ga,Mn)As is still under debate: does SWR stem from the \emph{surface} anisotropy (in which…
On the interpretation of the angular dependence of the FMR spectrum in heterogeneous ferromagnetic thin films
Maciej Kasperski, Henryk Puszkarski
We demonstrate that a multi-peak FMR spectrum, with lines corresponding to resonance in different ferromagnetic regions of a heterogeneous thin-film sample, can collapse to a singl…
Magnetic Composites: Magnonic Excitations vs. Three-Dimensional Structural Periodicity
M. Krawczyk, H. Puszkarski
This study deals with the spin wave spectrum in magnetic macrostructure (composed of two ferromagnetic materials) showing a 3D periodicity: spherical ferromagnetic grains disposed…
