Four distinct peaks are observed at 140, -26, -132 and -140 degrees C in the sigma x * against T -1 plot between 200 and -196 degrees C for (NH 4 ) 3 H(SO 4 ) 2 , corresponding to four different phase transitions of which the one at -26 degrees C is reported here for the first time. Data on doped samples reveal the charge transport mechanism in the crystal.
