1. Medidas magneto-óticas de tempos de relaxação Spin-Rede em KBr e nos halogenetos de Na e Cs e estudo de Dicroismo Circular Magnético do Ion Co++ em KCl. / Magneto-optical measurements of spin-lattice relaxation times in KBr, Na and Cs halides and Magnetic Circular Dichroism of Co++ dopped KCl.
In this work we describe a Magnetic Circular Dicroism Spectrometer wich was used in the following experiments: 1) We measured the spin-lattice relaxation time (T1) for F centers in NaCl, NaBr, CsBr and CsCl, at 1,8°K in magnetic fields up to 15000Gs. We verified the suitability of the theory of ref.(O8) to explain the differences observed for halides of
