Room-Temperature Valence Transition in a Strain-Tuned Perovskite Oxide

Vipul Chaturvedi, Supriya Ghosh, Dominique Gautreau +17

Cobalt oxides have long been understood to display intriguing phenomena known as spin-state crossovers, where the cobalt ion spin changes vs. temperature, pressure, etc. A very dif…
