His equation--when taken in the non-relativistic limit, it would account for the then unexplained gyromagnetic ratio (g = 2) of the Electron and this same equation emerged with explaining the Electron's spin.
[gamma] is the gyromagnetic ratio. [alpha] denotes the damping parameter.
Here [gamma] is the gyromagnetic ratio. The magnetization of materials we have in mind in this work is due to the spin of electrons, accordingly [gamma] = -1.76 x [10.sup.11] [Am.sup.2]/Js.
have inspired further search for an electromagnetic image of the electron since Carter [54] found that the parameter a couples to the mass m giving the angular momentum J = ma, and with the charge e giving an asymptotic magnetic momentum [mu] = ea, which results in exactly the same gyromagnetic ratio g = 2 as predicted by the Dirac equation [54].
where [alpha] is damping coefficient of ferromagnetic precession, [gamma] the gyromagnetic ratio, F = [[omega].sub.m]/[[omega].sub.r], [[omega].sub.m] the characteristic frequency of the ferrite, [[omega].sub.r] the FMR frequency of the ferrite, [M.sub.s] the saturation magnetization, [H.sub.0] is the applied magnetic field, [H.sub.a] the magnetocrystalline anisotropy field, and [N.sub.x], [N.sub.y], and [N.sub.z] are the demagnetization factor for x, y, and z directions, respectively.
The "Parallel Finite Element Micromagnetics Package (MAGPAR)" [26] has been used for simulation, working with the Landau-Lifshitz-Gilbert (LLG) equation of motion [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] with the magnetization [??], the saturation magnetization Ms, the effective field [[??].sub.eff], the gyromagnetic ratio [gamma], and a dimensionless damping constant [alpha].
where [gamma] is the gyromagnetic ratio of a proton (2.7 x [10.sup.8] [s.sup.-1] [T.sup.-1]), B is the strength of the magnetic field created by the nerve, and [DELTA]t is the duration of the rising phase of the magnetic field.
[omega]=[gamma][B.sub.0] where [gamma] is the gyromagnetic ratio and [B.sub.0] is the magnetic field strength.
