Ferromagnetic resonance in GaMnAs

Journal of Applied Physics, 2002
We 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 ...

Ferromagnetic Resonance

1986
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 ...

Cusp catastrophe in the ferromagnetic resonance spectrum of a layered ferromagnet

Physical Review B, 1990
En 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.

Spatial resonance in ferromagnetics

Journal of Magnetism and Magnetic Materials, 2017
Abstract 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 of EuO

Physical Review, 1964
Ferromagnetic 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.

Ferromagnetic Resonance in CrBr3

Journal of Applied Physics, 1962
Ferromagnetic 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 Ferrites

Nature, 1954
FERROMAGNETIC resonance studies have been made on polycrystalline specimens of the ferromagnetic systems (1 − x)(LiFe5O8)x(CdFe2O4), Li(Fe1−xAlx)5O8, Ni1−xZnxFe2O4 placed in resonant, cavities operating at frequencies of 9,470, 23,940 and 34,400 Mc./sec.

What is ferromagnetic resonance?

British Journal of Applied Physics, 1960
It is pointed out that two distinct resonance effects take place in ferrite samples at microwave frequencies, ferromagnetic resonance and an effect due to the shape of the specimen. The latter effect is called Kittel resonance in this paper. It is commonly supposed that the two effects are the same, but it is shown that this is not the case.

Characterization of Ferromagnetic Precipitates in Glasses by Ferromagnetic Resonance

1977
Ferromagnetic phases precipitated from iron-containing silicate glasses have been identified and characterized by studying the integrated intensity of the ferromagnetic resonance (FMR) as a function of sample temperature. The data show a completely different character for metallic iron precipitates and ferric iron spinel precipitates — a result which ...
