Dielectric properties of Iris-sarcosine bromide ((CH.NHCH.CO0H).CaBr.)which is isomorpltous to the ferroelectric crystal tris-sarcosine calcium claloride((CH,NHCH.C00H),CaC1., TSCC) have beexa iuax'estigated under high pressuredown to 4.2 K. Tlae hydrostatic pressure of' excel1ex?t q uality has been generated usinglaelium gas as a pressure traxasmitting medium. Tlte ferroelectric activity laas been coz?-firmed by the dielectric hysteresis loops. The pressure-tenaperature p]?ase diagram ofthe ferroelectric phase transition is deternuined from tlve peak of tlae dielectric con-stant of the #-plate in various isobaric rneasuremexats. The transition temperature iswell represented by an equation T.cf-(p -j?.)"' w1?ic1a is a well kutown relationsltipfor quantum ferroelectrics.[ ferroelectric, quantum ferroelectric, trns-sarcosine calciuxn bromide, ]] (CH.NHCH.COO]-I),CaBrz, TSCC, high pressurel
