“…This approximation (a more rigorous development of which is beyond the scope of this letter) allows us, e.g., to understand qualitatively the presence of quasi-uniform resonance modes confined above and below the antidot. 27,35 Moreover, as would be expected from Fig. 1(c), the regions left and right of the antidot reveal an increase in the local frequency, which then tends in a graded fashion 24 towards the FMR frequency of the continuous film (2.98 GHz).…”

“…The results presented here are applicable to the interpretation of the magnetization dynamics in magnonic antidot arrays (which have been extensively studied, e.g., in Refs. [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46], while also elaborating the interpretation of the spin-wave scattering that was experimentally and theoretically studied in Ref. 25.…”

The following information can be accessed with the help of such resonance experiments. (i) Electrical structure of point defects by looking at the absorption in a thin structure. (ii) The line width with the movement of spin or surroundings isn't changed. (iii) The distribution of the magnetic field in solid by looking at the of the resonance line position (chemical shift and etc.). (iv) Collective spin excitations. Ferromagnetic Resonance-Theory and Applications 2 The atoms of ferromagnetic coupling originate from the spins of d-electrons. The size of μ permanent atomic dipoles create spontaneously magnetized. According to the shape of dipoles materials can be ferromagnetic, antiferromagnetic, diamagnetic, paramagnetic and etc. Ferromagnetic resonance (FMR) technique was initially applied to ferromagnetic materials, all magnetic materials and unpaired electron systems. Basically, it is analogous to the electron paramagnetic resonance (EPR). The EPR technique gives better results at unpaired electron systems. The FMR technique depends on the geometry of the sample at hand. The demagnetization field is observed where the sample geometry is active. The resonance area of the sample depends on the properties of material. The FMR technique is advantageous because it does not cause damage to materials. Also, it allows a three dimensional analysis of samples. The FMR occurs at high field values while EPR occurs at low magnetic field values. Also, line-width of ferromagnetic materials is large according to paramagnetic materials. Exchange interaction energy between unpaired electron spins that contribute to the ferromagnetism causes the line narrowing. So, ferromagnetic resonance lines appear sharper than expected. The FMR studies have been increased since the EPR was discovered in
