Pressure Induced Abnormal Phase Transition in Perovskites Compounds

Caption

Chemical intuition tells us that pressure tends to increase number of coordination, and hence usually makes a structure ordered that is especially true for perovskite like compounds. However, in the recent discovered Y2CoIrO6 a A2B'B''O6 type double perovskite compound, researchers found exceptional pressure induced B-site order to disordering transition phenomena.
