Typically, this technology utilizes the ultrafast laser to excite the
spin wave in the magnetic nanostructures and accordingly switch its magnetization state [2, 3].
Spin wave devices are advantageous over their optical counterparts because they are more scalable due to their wavelengths being shorter than light.
Apart from the contribution of the lattice and the electron to the specific heat, the hyperfine structure and
spin wave should be considered generally.
However, even if we would assume, as is conventional, that ("clothed") partons within the proton are defined, the proton wave function, [PSI], could not be factorized into separate valence quark
spin wave functions (|[[chi].sub.1] >, |[[chi].sub.2]>, |[[chi].sub.1]>) as this would not result in an eigenstate of the strongly spin-dependent Hamiltonian, entering the energy eigenvalue equation
He and his contributors describe ferrous magnets,
spin waves that play an important role in very small magnetic systems, magnetic sensors, magnetic nano-contacts, quantized models in lateral confinement, Brillouin light scattering studies of spin dynamics (in patterned nano-elements from a single layer to multilayered structures), non-uniform magnetization dynamics in ultra-small ferromagnetic planar elements, mode structures of ferromagnetic squares,
spin waves in the inhomogeneous internal field of nano-structured rings, and localized
spin wave modes excited by polarized current.
We have developed approximate expressions for the neutron
spin wave function and the projection of the spin on the field as the neutron moves in space where the field direction and magnitude changes.
A well known example of the Nambu-Goldstone mode is the
spin wave or magnon in a ferromagnet.
(4) The sigma model part essentially represents
spin wave modes, whereas the topological part implies the breaking up of the configurations into distinct topological sectors.
