Strong magnets with ordered structures
WebFerromagnetism. Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example. Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets. WebJan 23, 2024 · Strong ferromagnetic correlations were found to develop in the superconducting state, but no long range order was present. The first examples of true long range magnetic order coexisting with superconductivity were provided by the ternary Chevrel-phase superconductors (RMo 6 S 8) and related (RRh 4 B 4) compounds.
