AbstractAbstract
[en] We have undertaken a study of the electronic properties of a new organic conductor, (BEDT-TTF)2BrO4, using magnetic resonance techniques and also the organic superconductor (BEDT-TTF)2I3. Proton magnetic resonance experiments on (BEDT-TTF)2BrO4 have resolved individual proton lines without the aid of line narrowing techniques. The electron spin resonance line is very narrow and shows a frequency independent low temperature broadening in the low temperature regime. The ESR broadening is strongly pressure dependent, being suppressed to lower temperature with the application of pressure. We have used radio frequency techniques to monitor the pressure dependence of the superconducting transition temperature, T/sub c/, in (BEDT-TTF)2I3 and find that T/sub c/ is suppressed to below 1K with the application of less than 0.5 kbar of pressure. In addition, we find a magnetic transition at 7K above a pressure of .5 kbar. 4 references, 7 figures
