Spin Waves in the Dilute Heisenberg Ferromagnet
The energy of long wave length spin waves in dilute Heisenberg ferromagnets is calculated. It is shown that spin waves can exist only within an infinite cluster of magnetic spins and that such spin waves are mechanically stable. Heuristic arguments based on dimensionality of the infinite cluster imply that there is no thermal instability of the type discussed by Mermin and Wagner. Thus, the cri...
متن کاملEvidence for spin selectivity of triplet pairs in superconducting spin valves.
Spin selectivity in a ferromagnet results from a difference in the density of up- and down-spin electrons at the Fermi energy as a consequence of which the scattering rates depend on the spin orientation of the electrons. This property is utilized in spintronics to control the flow of electrons by ferromagnets in a ferromagnet (F1)/normal metal (N)/ferromagnet (F2) spin valve, where F1 acts as ...
متن کاملDipolar Recoupling and Decoupling
In solid state nuclear magnetic resonance spectroscopy, the magic angle spinning technique is often used to remove anisotropic interactions and generate high resolution spectra. However, these interactions contain valuable information about molecular structure and dynamics. In particular, the dipole-dipole coupling strength between two spin-1/2 nuclei is a direct reflection of their interatomic...
متن کاملMAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON
The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...
متن کاملSpin correlation in kagomé ice state : neutron scattering study of the dipolar spin ice Dy 2 Ti 2 O 7 under magnetic field along [ 111 ]
Spin correlation in kagomé ice state: neutron scattering study of the dipolar spin ice Dy 2 Ti 2 O 7 under magnetic field along [111] Abstract We have investigated the kagomé ice state in the frustrated pyrochlore oxide Dy 2 Ti 2 O 7 under magnetic field along a [111] axis. Spin correlations have been measured by neutron scattering and analyzed by Monte-Carlo simulation. The kagomé ice state, w...
