THE TEMPERATURE DEPENDENCE OF THE SHAPE OF PARAMAGNETIC RESONANCE LINES. PART II

Abstract

At sufficiently low temperatures the temperature dependence of the shape of paramagnetic resonance lines of crystals is mainly due to the temperature dependence of the occupation numbers of the energy levels of the system of interacting paramagnetic ions. The theory of this effect, recently discussed by the authors, is extended to the case of anisotropic exchange interaction and arbitrary shape of the paramagnetic crystal.
