An MRI term for a measure of the net magnetic properties of an object or particle, which is a sum of the intrinsic spins of the nuclei that have an associated magnetic dipole moment interacting with a magnetic field.
where T is the magnetic anomaly in nanotesla (nT), m is the target magnetic moment in Ampere-meter (2) ([Am.sup.2]), r is distance between observation spot and dipole in meters (m), and n is a measure of the rate of decay with distance or falloff rate (n = 3 for dipole; n = 2 for monopole).
For the sake of completeness, we stress that the effective neutrino magnetic moment [[mu].sub.v] is expressed through neutrino amplitudes of positive and negative helicity states, e.g., the 3-vectors [a.sub.+] and [a.sub.-] and the neutrino transition magnetic moment matrix, [lambda], in flavour basis, as [37,58]
Likewise, the origins of ferromagnetism in Cu:ZnO remain unidentified as neither Cu nor ZnO is intrinsically magnetic, meaning that one defect type must exist to induce the magnetic moments and another to mediate them.
The position vector coordinates of equations (3) and (4) are aligned with the magnetic moment coordinates of the dipolar source (hence the need for rotational matrix R to align with the [B.sub.Obs] coordinates).
