The transport, magnetic and thermodynamic properties of RuSr{sub 2}GdCu{sub 2}O{sub 8} and related compounds are reviewed. These indicate uniform coexistence of superconductivity ({Tc} = 46K) and ferromagnetism (T{sub M} = 132K) in which the former arises in the CuO{sub 2} planes and the latter in the RuO{sub 2} planes. The earliest data indicated a typical underdoped cuprate with local Ru moment ferromagnetism, the absence of pairbreaking and transport properties dominated by the CuO{sub 2} planes. However, recent results suggest a more complex scenario of itinerant ferromagnetism and exchange coupling between the CuO{sub 2} and RuO{sub 2} layers.
