Kind: research · Impact: low

## In brief

- A first-principles study investigates cubic XEuO3 perovskites with X = K, Rb, Cs and Fr.
- The study examines half-metallicity and other physical properties of these materials.
- The authors frame the materials as potential candidates for opto-spintronic applications.

## Why it matters

Half-metallic materials are candidates for spintronic devices, where electron spin carries information, so computational screening of new perovskites can guide which compounds merit experimental work.
