The relationship between the magnetic moment and the angular momentum is called the "gyromagnetic ratio" and has the value "e/2m".
The results involve the bare gyromagnetic ratios and experimental data are from [44].
where [gamma] is a physical constant (the gyromagnetic ratio) and the magnetic induction B may be written as a purely imaginary quaternion, so the evolution of the above system describes a rotor with angular velocity [OMEGA] = [gamma]B.
where [T.sup.1.sub.2] is the relaxation time of fluid (ms), [[rho].sub.2] is the transverse surface relaxation strength ([micro]m/ms), s is the pore surface area ([cm.sup.2]), V is the pore volume ([cm.sup.3]), [[rho].sub.2]s/V is the transverse surface relaxation rate, D is the diffusion coefficient, [gamma] is the gyromagnetic ratio, G is the gradient of the magnetic field, is the gradient of the magnetic field (Gs/cm), [T.sub.E] is the echo time (ms), and D[([gamma][GT.sub.E]).sup.2]/12 is the diffusion relaxation rate.
The susceptibility effects encountered in [sup.13]C MR are considerably smaller relative to [sup.1]H MR by virtue of the [sup.13]C gyromagnetic ratio, which is one-fourth that of [sup.1]H.
where [T.sub.2B] is the free relaxation time, ms; [rho] is a constant representing the transverse relaxation strength, [micro]m/ms; S/V is the specific surface area which relates to the pore size; D is the diffusion coefficient, [micro][m.sup.2]/ms; [gamma] is the gyromagnetic ratio, MHz/T; and G is the field-strength gradient, Gs/cm; [T.sub.E] is the interecho spacing, ms.

In [20], Lin and Chui have developed a complete theory to solve Maxwell equations for gyromagnetic particles.
where [gamma] = 267 x [10.sup.6] radians/(s T) is the gyromagnetic ratio for protons and At is the time over which the phase accumulates (the duration of the magnetic field for brief biomagnetic signals or a duration related to the MRI pulse sequence such as the echo time for long duration biomagnetic signals).
[f.sub.FMR] increases with increasing [H.sub.k], where [H.sub.k] is the magneto- crystalline anisotropy field, [M.sub.s] the saturation magnetization, and [gamma]/2[pi] the gyromagnetic constant (2.8MHz/Oe).
Analogical models of ferrite-dielectric (gyromagnetic) waveguides are used occasionally.
