On the temperature dependence of the paramagnetic resonance line shape function in the case of the Ising model Yu-yang, Lee

Abstract

The adequacy of the approximation method used by McMillan and Opechowski (1960) in their theoretical study of the temperature dependence of the paramagnetic resonance line shape function is very difficult to ascertain for the case of a typical paramagnetic crystal. For this reason the approximation method has been investigated, in this thesis, for the very simple case of the one-dimensional Ising model. Exact expressions for the line shape function of the model are compared with expressions obtained by the above mentioned approximation method. The agreement between the two expressions is found to be very good for all temperatures, and in particular, for extremely low temperatures.
