Paramagnetic relaxation in single crystals of salts of the ions Mn++, Fe+++, and Cu++as a function of their orientation in a parallel constant magnetic field at room temperature

Abstract

The paramagnetic absorption curves of single crystals of salts of the ions Mn++, Cr+++, Fe+++, and Cu++in an oscillating field of frequency 10.5 Mc are given as a function of orientation in a constant magnetic field H. The results are reported of determinations of spin-lattice relaxation times in these single crystals. The Brons-Van Vleck formula is checked. © 1968 The Faraday Press, Inc.
