Abstract - The ruthenocuprates are high temperature superconductors, which have raised a substantial interest due to the simultaneous presence of the transition metal magnetism and superconductivity. The compounds represent a complex and experimentally challenging research arena, with interesting recent experimental developments. Without striving for completeness, the author reviews some key properties of RuSr₂RECu₂O₈, RuSr₂RE_2-xCe_xCu₂O_10-y, and of few derivative compounds of the ruthenocuprate family.
