Abstract
AbstractFor paramagnetic ions the electronic spin—spin and spin—lattice relaxations taking place independently are well known. In the first part of this paper a new type of “mixed spin relaxation process” has been considered in which dipolar spin—spin and spin—phonon (or orbit—lattice) interactions are jointly needed to effectively produce a relaxation transition, and the rate‐expression for this process has been obtained on phenomenological considerations. In this part of the paper the “mixed spin relaxation rates” for substitutional paramagnetic Fe2+(5D) ions in zinc carbonates are explicitely calculated and then compared with experimental data obtained from the analysis of the Mössbauer magnetic hyperfine spectra of this system at liquid helium temperatures. It appears that at low temperatures this process also provides a competing mode for the exchange of energy between electronic spins and phonons.
