Regulating the metal-insulator transition of REBaCo <sub>2</sub> O <sub> 5+ <i>δ</i> </sub> combining RE-substitution and anion control
Enabling abrupt MITs for REBaCo 2 O 5+ δ relies on the synergistic coordination between the RE ionic radius-induced CoO 6 octahedral distortion and the oxygen vacancy-modulated Co valence state to reach a low structural symmetry, with δ approaching 0.5.
