The observation of bulk superconductivity in Rhombohedral ReO3 under pressure
S. Huyan, R. F. S. Penacchio, L-L. Wang +10
Understanding how lattice geometry enables superconductivity in oxides remains a central challenge. Here, we report a systematic study of ReO3 up to 80 GPa. Synchrotron X-ray diffr…
Suppression of the valence transition in solution-grown single crystals of EuPtAl
