When traveling through the field, the spin-up electrons get the additional energy [micro]H, where p stands for the Bohr magneton
, whereas the spin-down ones release the same energy.
The magnetic susceptibility data in this figure can be well fitted with the Curie law: [chi] = [[chi].sub.0] + C/T, where C= N[[mu].sup.2.sub.eff]/3[k.sub.B] is the Curie constant, N is Avogadros's number, [[mu].sub.eff] is the effective magnetic moment ([[mu].sub.eff] = [P.sub.eff][[mu].sub.B]), represents the effective Bohr magneton
number, [[mu].sub.B] is the Bohr magneton
, [k.sub.B] is the Boltzmann constant, and [[chi].sub.0] is the temperature independent susceptibility term.
The electron behaves not only as the unit of electric charge but also as the unit of magnetic charge or magneton
. Several important physicists, including Webster, Gilbert, Grondahl and Page, conducted studies that supported Parson's Ring Electron Model.

where N, T, [k.sub.B], [[mu].sub.B] g, N, [z.sub.1], [z.sub.2] are the number of spins, temperature, Boltzmann constant, Bohr magneton
, spin factor, total number of spins, and coordination numbers, respectively [9,13].
where N is the number of paramagnetic centers per gram of the sample, [g.sub.s] is the electron spin factor (the Lande factor), [[mu].sub.B] is the Bohr magneton
, [k.sub.B] is the Boltzmann constant, T is the absolute temperature, [H.sub.z] is the magnetic field directed along the z axis of the reference-fixed frame, and s = 1/2.
Subjects were scanned in a 1.5 T scanner (Siemens, Magneton
Vision, Erlangen, Germany) with a commercially available TX/RX head coil.
H = the magnetic field; [upsilon] = the microwave frequency; h = the Planck constant and [beta] = the electron Bohr magneton
[[beta].sub.1] - non-dimensional slip coefficient; [epsilon] - porosity; [phi] - volume fraction of nanoparticles; [gamma] - Sommerfeld constant, [Jkg.sup.-1][K.sup.2]; [mu] - dynamic viscosity, Kg [s.sup.-1][m.sup.-1]; [[micro].sub.B] - Bohr magneton

Images were acquired on a Siemens Magneton
Verio 3 T MRI clinical scanner (Siemens Healthcare GmbH, Erlangen, Germany).
where [g.sub.e] [approximately equal to] 2 is the loosely trapped electron g- factor (this is quite different from the DMS where instead of [g.sub.e] in (1) there is [g.sup.*], the negative g-factor of the band electron) and [g.sub.Mn] [approximately equal to] 2 is the [Mn.sup.2+] g-factor, [alpha] is the exchange integral, positive for ferromagnetic interaction between the electron and [Mn.sup.2+] ion, is the Bohr magneton
, and [chi] is the static magnetic susceptibility.
