Magnitude and the microwave Faraday effect related to conduction electron spin resonance of lithium

Abstract

A comparison is made between the experimental and calculated magnitudes of the microwave Faraday rotation and ellipticity related to conduction electron spin resonance (CESR) of a lithium dispersion in paraffin wax. Experimental magnitudes are taken from a previous paper by Theobald et al. (1972), whereas calculated magnitudes are obtained from equations which have been transported from the classical paramagnetic case to the special case of CESR. In this trans position, the static susceptibility is in fact replaced by the conduction electron spin susceptibility of the effective lithium sample. The effective volume of lithium was only a part of the total volume, because the skin depth was smaller than the size of particles at the frequency and temperature of the experiment. Finally, a good agreement is found between the experimental and calculated magnitudes of the CESR Faraday effect of lithium.
