Ferromagnetic resonance in amorphous ferromagnet

Solid State Communications, 1984
Abstract The peculiarities of the ferromagnetic resonance of an amorphous ferromagnet in which a certain number of atoms forms the two-level systems are studied. The logarithmic dependence upon the temperature and the applied magnetic field of the frequency shift of the ferromagnetic resonance is obtained.

Ferromagnetic resonance in weakly electrically conducting ferromagnets

Czechoslovak Journal of Physics, 1983
For 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.

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 Resonant Tunneling Diode

Physica Scripta, 2002
We have studied theoretically the magnetotransport in a ferromagnetic resonant tunneling diode (FRTD), where alternating magnetic Ga1-xMnxAs and non-magnetic GaAs and AlAs layers give rise to strongly spin-polarization dependent electronic transport.

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 ...

Broadband ferromagnetic resonance spectrometer

Review of Scientific Instruments, 2003
The continuous wave ferromagnetic resonance (FMR) spectrometer operating in multioctave (0.05–40 GHz) frequency range has been built to investigate the magnetic properties of thin ferromagnetic films in the temperature range of 4–420 K. The spectrometer has two probeheads: one is the X-band microwave reflection cavity used to perform express room ...

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 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 Force Microscopy

2006
The Magnetic Resonance Force Microscope (MRFM) is a novel scanning probe instrument which combines the three-dimensional imaging capabilities of magnetic resonance imaging (MRI) with the high sensitivity and resolution of atomic force microscopy (AFM). In the nuclear magnetic resonance (NMR) mode or the electron spin resonance (ESR) mode it will enable

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.
