We have developed a new high-field and low-temperature ESR system under high pressure. Using this system, several different quantum spin systems have been studied. We will report about the result of the high-field ESR measurements of hexagonal ABX3-type compound CsCuCl3 for B∥c under pressure. The increase of the critical field was observed for the first time by our high-field ESR measurement under 3.2 kbar. The origin of the increase of the critical field by pressure in CsCuCl3 will be discussed.
