Inside Back Cover: Frenkel‐Defect‐Mediated Chemical Ordering Transition in a Li–Mn–Ni Spinel Oxide (Angew. Chem. Int. Ed. 27/2015). Issue 27 (1st June 2015) - Ryoo, Hyewon
Abstract AxByOz‐type complex oxides with multiple cations show different chemical ordering for the cations at the A and B sites. In their Communication on page 7963 ff., S.‐Y. Chung et al. report the configurational ordering in an AB2O4 spinel by the formation of Frenkel defects at octahedral sites as a transient state. The role of such point defects in crystals is not confined merely to mass and charge transport but extends to phase transitions.
