I. INTRODUCTION In recent years, the A2BX4-type crystals have attracted much attention, for they have a series of phase transitions, especially the incommensurate phase in a certain temperature range. K2SeO4 is the most typical in this family, which has already been widely investigated. Rb2ZnCl4 is another member in this family, whose property and
