Abstract
The pressure dependence of the first order and the second order transition temperature (Tc1 and Tc2) for MAg4I5 (M=K and NH4) is measured in the range of pressure up to 7 kbar. The variations of Tc1 and Tc2 with pressure (p) show a large quadratic pressure dependence: (p-p0i)2=Ai(Tci-Tc0i), where p0i, Ai and Tc0i (i=1, 2) are the pressure independent constants. The correlation of the pressure dependence of Tc1 and Tc2 for MAg4I5 (M=K, NH4 and Rb) is clarified.Keywords
