| Outline of Final Research Achievements |
Ir of SrIrO3 and CaIrO3 film on SrTiO3(001) substrate was substituted by Sn to suppress band width and introduce inhomogeneity of potential. In SrIrO3, substitution yielded transition into magnetic insulator at low temperature. On the other hand, Sn substituted CaIrO3 already showed insulating behavior above magnetic transition temperature. We concluded that inhomogeneity is the direct cause of insulating behavior of Sn substituted CaIrO3 while it is not in Sn substituted SrIrO3.
