The hybrid-type piston-cylinder pressure cell whose maximum pressure reaches 4GPa was used. In this study, we obtained ESR spectra at 2.3GPa successfully, which can never be obtained by the single-layer piston-cylinder pressure cell. The minimum detectable spin number was estimated to be the order of 1012spins/G. Moreover, it is shown that the sensitivity can be improved by two orders of magnitude using the field modulation technique. This high-pressure ESR technique is a promising one to achieve the sensitivity and the high pressure simultaneously.
