Electron spin resonance of impurities in magnetic insulators
Abstract
It is possible to observe and very useful to study the electron spin resonance of impurities in paramagnetic hosts. Among the interesting phenomena observable and measurable in these studies are: (a) symmetric and antisymmetric exchange interactions between the impurities and the hosts determined from the indirect superhyperfine interactions, pseudo-Zeeman interactions and pseudo crystal field effects, (b) the Jahn-Teller induced random strains effects resulting in the magnetic field dependence of the fine structure linewidths, and (c) the nature of the dynamical interactions of the hosts manifested in the lifetime broadenings of the impurity spectra. © 1982.
