We have developed a low-temperature ESR system under pressure, which has the frequency region above 70 GHz, the pulsed magnetic field up to 16 T and the pressure region up to about 3.5 kbar. A suitable pressure-calibration method using the change of the ESR of ruby under pressure has been also developed. We can determine the pressure and observe ESR signals of a sample at the same time. The high-field ESR measurements with the pulsed magnetic field up to 16 T have been performed on triangular antiferromagnet CsCuCl3 for H∏c around 6 K at 1 bar and at 3.1 ± 0.6 kbar in the frequency region from 120 GHz to 370 GHz. We observed the increase of the phase transition field from the umbrella-type configuration to the coplanar configuration due to the quantum fluctuation and the increase of the antiferromagnetic gap under pressure. The possible origin of this increase of the phase transition field was discussed in connection with the recent magnetization measurements under pressure.
