Abstract

ESR line shapes arising by spin-lattice interaction have been examined for magnetically dilute solids; it is found that the finite mean free path for phonons in a real crystal for S=1/2 implies that Bloch's phenomenological equations are applicable, which give the line a Lorentz shape. The secular terms in the spin-lattice interaction for an ideally harmonic crystal give rise to a narrow line of nearly δ-function form at the center and gaussian shape at the flanks.
