Our paper exploring the evolution of the structural and electronic phases of (Sr1-xCax)2IrO4 appeared today in Physical Review B.  This study unveiled the effect of chemical pressure on the structural stability, magnetism, and insulating ground state of the spin-orbit Mott insulator Sr2IrO4.  A series of distinct structure types appear with increasing Ca-content, each suggestive of reduced electronic dimensionality and are potential hosts of unconventional magnetism.
