ABSTRACT
Structural and electrical properties of c-axis oriented epitaxial Sr[sub 2]Rh[sub 1-x]Ru[sub x]O[sub 4] (0≤x≤ 1) films were systematically investigated. The composition-spread films were fabricated on a temperature gradient (LaA1O[sub 3])[sub 0.3](Sr[sub 2]A1TaO[sub 6])[sub 0.7] substrate to quickly optimize the growth temperature for a high-quality crystalline film having each composition (x). An anomalous c-axis length dependence on x was observed, and it was accompanied by a distinct change in electric property, that is, a metal-insulator-metal transition.
