摘要：

Calorimetric measurements of Cs2ZnI4 showed four distinct phase transitions at 117, 108, 104 and 94 K. The shape of the observed specific heat peaks indicates that those at 108 and 94 K are first order in nature. This sequence is in agreement with previous results using different experimental techniques, and supports the hypothesis that the phase transition sequence of Cs2ZnI4 is the same as that of Cs2HgBr4 and can be written as GRAPHICS
