Separating of Lattice and Impurity Contributions in Nuclear-Spin-Lattice Relaxation Under Steady Saturation Conditions

Impurity Nuclear Spin–Lattice Relaxation Suppression and Charge Exchange of Chromium Ions in a γ-Irradiated Ruby Crystal

“…A rather strong additional magnetic (as well as acoustic or electric) steady saturation produces local heating of the nuclear spin system, corresponding to ␣ loc ϭ 0 while ͗␣͘ is equal to a steady-state value ͗␣͘ st Ͼ 0 (18). This means that the regions near impurities became warmer than the spin system in the main crystal volume and the inequality [1] is inverted.…”
