Paramagnetic Ions

In some substances such as metals, semiconductors, paramagnetic solutions, the main mechanism of relaxation for the nuclear spins results from their coupling with unpaired electronic spins in fast relative motion with respect to them. The electronic spins will be those of conduction electrons in metals or semiconductors, of free radical or paramagnetic ions in paramagnetic solutions. The thermal reservoir or ‘lattice’ which provides or takes up the energy required for simultaneous electron-nucleus flips caused by the relaxation, is the kinetic energy of their relative motion.

In this chapter, some prospects in the field of electron and nuclear spin dynamics are outlined. Particular emphasis is put ona situation where the hyperfine interaction is so strong that it leads to a qualitative rearrangement of the energy spectrum resulting in the coherent excitation transfer between the electron and nucleus. The strong coupling between the spin of the charge carrier and of the nucleus is realized, for example in the case of deep impurity centers in semiconductors or in isotopically purified systems. We also discuss the effect of the nuclear spin polaron, that is ordered state, formation at low enough temperatures of nuclear spins, where the orientation of the carrier spin results in alignment of the spins of nucleus interacting with the electron or hole.
