Paramagnetic Spin-Lattice Relaxation via the Anharmonic Raman Process
Abstract
The anharmonic Raman process, which was shown by Van Kranendonk and Walker to be important in the case of nuclear quadrupolar relaxation, is shown here to be of sufficient magnitude to explain the Raman relaxation rates of the paramagnetic ions Cr3+ and Ni2+ in MgO. This new relaxation process involves the anharmonic three-phonon interaction.
