Magnetic composites, effective medium

Medium effects include that of bulk susceptibility, which depends on the geometry of the sample and the composition of the solution. For a perfectly spherical sample, the nuclear magnetic shielding contribution a of the bulk susceptibility is zero. For other shapes a susceptibility correction is needed because of polarization of the sample near the liquid surface. For an infinitely long cylinder, oriented with the cylindrical axis perpendicular to the direction of the magnetic field as in an electromagnet, the frequency shift due to bulk susceptibility of a pure solvent (as for a molecule observed in infinite dilution) is related to the molecular magnetic susceptibility x, or the volume susceptibility Xv of the solvent by... [Pg.42]
