Perturbation theory and spin temperature in the saturation of spins
… to nuclear resonance and Redfield's theory of spin temperature in the rotating frame. We show that, although Bloembergen, Purcell, and Pound's approach is correct for perturbations of short duration, for long lasting perturbations, the state of a system is significantly changed, perturbation …

Dynamic Nuclear Polarization in Samarium Doped Lanthanum Magnesium Nitrate
… effect have been derived in detail using the spin temperature theory and the complete expression for the steady-state enhancement of the nuclear polarization has been calculated. For well-resolved solid effect transitions at microwave frequencies Ï ~ Ï <sub>e</sub> ± Ï <sub>n</sub>, the …

Thermometry and cooling of ultracold atoms in an optical lattice
… separated the atoms into regions of opposite spin, with a boundary region of mixed spin in the center. In the presence of an optical lattice, the width of this region was found to be proportional to the system's temperature and inversely proportional to the strength of the magnetic field. This …
