Spin State Control of the Perovskite Rh/Co Oxides

Spin State Control of the Perovskite Rh/Co Oxides

We show why and how the spin state of transition-metal ions affects the thermoelectric properties of transition-metal oxides by investigating two perovskite-related oxides. In the A-site ordered cobalt oxide Sr3YCo4O10.5, partial substitution of Ca for Sr acts as chemical pressure, which compresses...
