A Technique for the Measurement of the Faraday Effect in Pulsed Magnetic Fields at Low Temperatures
This chapter describes a technique for measuring the spin-lattice relaxation time in paramagnetic crystal and the Faraday effect in different materials. The technique was suggested by Prof. Toraldo di Francia of the University of Florence, and an apparatus based on this technique has been developed for use in the Synchrotron Laboratory at Frascati, Italy. The sample is put in a pulsed magnetic field whose duration is comparable to (or larger than) the relaxation time of the spin-lattice of the crystal. By measuring the magnetic field H versus time and the magnetization of the specimen it is possible to get the value of t as a function of temperature and magnetic field.
