Crystal Structures and Properties

Single crystals of LaRhO3, PrRhO3, NdRhO3, SmRhO3, EuRhO3, and TbRhO3 have been grown for the first time using a K2CO3 flux. All the compounds were found to crystallize in the orthorhombic space group Pbnm (No. 62) and adopt the GdFeO3 distorted perovskite structure type. Transition toward a pseudo-cubic cell is noted as the rare earth cation size increases.
