In the previous chapters we covered theoretical aspects of magnetism and magnetization dynamics, as well as practical aspects of implementation of the SLL equation in efficient softwares. In this chapter we focus on the most natural and frequently used experimental method to study magnetization dynamics, namely ferromagnetic resonance (FMR).

Ferromagnetic resonance in GaMnAs
Journal of Applied Physics, 2002We report a systematic study of ferromagnetic resonance (FMR) on thin films of the ferromagnetic semiconductor GaMnAs grown by low temperature molecular beam epitaxy. Pronounced shifts of the FMR line are observed towards fields above and below the g=2.00 resonance position for the magnetic field orientations perpendicular and parallel to the plane of ...

Cusp catastrophe in the ferromagnetic resonance spectrum of a layered ferromagnet
Physical Review B, 1990En utilisant une theorie stroboscopique classique de resonance ferromagnetique, on montre que le spectre presente un point de rebroussement et des catastrophes d'ordre eleve. L'irregularite du pic provient de l'interaction des magnons.

Abstract Ferromagnetic resonance (FMR) is used in the identification of the magnetic state of materials, the quantitative determination of static magnetic parameters, and the determination of microwave losses. This article describes the theory of ferromagnetic resonance and provides information on reflection spectrometers, microwave ...

Ferromagnetic Resonance of EuO
Physical Review, 1964Ferromagnetic and paramagnetic resonance has been observed with single crystals of europous oxide. The frequencies used were 23.8 and 27.5 Gc/sec, and the temperatures ranged from 1.5 to 300\ifmmode^\circ\else\textdegree\fi{}K. The linewidth increased from about 800 Oe at low temperatures to about 1400 Oe at room temperature.

Spatial resonance in ferromagnetics
Journal of Magnetism and Magnetic Materials, 2017Abstract Phenomenological Landau theory is used to study an interaction between structural and magnetic subsystems in a crystal in the vicinity of phase-transition lines. It is demonstrated that the twist-induced severe plastic deformation results in a forced onset of inhomogeneous distribution in the magnetic subsystem.

Ferromagnetic Resonance in CrBr3
Journal of Applied Physics, 1962Ferromagnetic resonance has been observed in single crystals of anhydrous chromium tribromide using frequencies of 20 to 27 kMc. At 1.5°K a g value of 2.006 is found along with a uniaxial anisotropy, K=9.4×105 ergs/cm3. Linewidths as narrow as 3.5 oe have been observed at 1.5°K.

Ferromagnetic resonance in the nonhomogeneous intermediate state of a ferromagnet
Physica B: Condensed Matter, 1999Abstract A microscopic theory of ferromagnetic resonance in the nonhomogeneous intermediate state (domain structure) of an ellipsoid is developed. It is shown that dipole–dipole magnetic interaction defines the dependence of ferromagnetic resonance frequencies on applied magnetic field.

Ferromagnetic resonance in weakly electrically conducting ferromagnets
Czechoslovak Journal of Physics, 1983For low electrically conducting anisotropic ferromagnetic metals an analytical FMR theory was deduced, which considers the influence of dielectric permittivity (the displacement current in Maxwell equations); it is applicable especially at frequencies in the mm or far infrared region.
