magneton

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 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].

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.

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.
