LiTi 2 O 4 has been the subject of considerable experimental and theoretical interest since the discovery of its superconductivity by Johnston et al. 1 This unique, low‐ T c (11.2 K) spinel oxide superconductor exhibits unusual characteristics, and interestingly, it presents properties that depend on various defects of the spinel structure. This article reviews experimental and theoretical studies of LiTi 2 O 4 and discusses the basic, unresolved issues regarding the physics of this system. Special emphasis is given to methods for preparing the compound and to the structure‐properties relationship.
