This paper aims at reviewing the progress within APFIM of high-Tc superconductors during the past ten years. Most of the studies has dealt with the compound YBa2Cu3O6+δ (YBCO), but many other compounds have also been investigated. The development of methods for specimen preparation, FIM imaging and APFIM analysis is described, and studies of interfaces and oxygen ordering are reviewed.
