Abstract :
The normal-state ESR properties of two new organic superconductors, β″-(BEDT-TTF)2SF5CH2CF2SO3 and κL′-(BEDTTTF) 2Cu(CF3)4(DBCE) are reported. Both compounds showed metallic properties below 140 K. The former gave ESR line widths and g-values of 23 to 34 G and 2.004 to 2.012, respectively. The latter gave line widths and g-values of 45 to 58 G and 2.006 to 2.012, respectively. The orientation-dependent line widths and g-values of the κL′-phase were found to be similar to that of the κ-(ET)4Hg3Br8 but not to the κL-phases in general.
