A Note on the Paramagnetic Relaxation

Abstract

Introducing the spin-spin relaxation time and the spin-lattice relaxation time in Bloch’s equation simultaneously, we have calculated the relaxation equation of paramagnetic substances. As the contribution from the spin-spin relaxation to the imaginary part of the complex susceptibility, a term proportional to (1−F)² instead of (1−F) given by Brower has been obtained. Our theory explains the experimental results obtained by Gorter et al for the dependence of the spin-spin relaxation time on the static field strength.
