paramagnetic relaxation

paramagnetic relaxation

[¦par·ə·mag′ned·ik ‚rē‚lak′sā·shən]
(electromagnetism)
The approach of a system, which displays paramagnetism because of electronic magnetic moments of atoms or ions, to an equilibrium or steady-state condition over a period of time, following a change in the magnetic field.

* The sensor's magnetic invisibility makes it suitable for use in super paramagnetic relaxation measurements in which extremely small magnetic fields are measured.
The Mossbauer spectra of [Mg.sub.0.5][Zn.sub.0.5][Fe.sub.2][O.sub.4] sample show a paramagnetic doublet, which is due to the super paramagnetic relaxation, in other words, some particles are a single domain.
However, for blood flow independent effects in MRI, the paramagnetic relaxation from spin-trapped NO might provide a new fMRI contribution using 5-diethoxyphosphoryl-5-methyl-1-pyrroline-N-oxide (DEPMPO).
