Rapid strides in the development of composite superconducting materials have encouraged the widespread use of high‐field superconducting magnets in high‐energy physics, fusion and medical imaging—fulfilling Kamerlingh Onnes's 75‐year‐old vision.

Superconducting quantum interference devices are so sensitive to magnetic flux that they can map the tiny magnetic fields emanating from the human brain and detect the submicroscopic motions of gravity‐wave detectors.

Recent advances on the road to superconducting computers include novel operating designs for logic and memory circuits as well as stable and reliable devices made entirely from refractory materials.

High‐speed analog devices that make use of the unique properties of superconducting tunnel junctions and transmission lines are finding application in microwave receivers, signal processors and voltage standards.

Compounds of rare earth and actinide elements with partially filled f‐electron shells show superconductivity induced by magnetic fields, carried by “heavy” electrons and destroyed below a second critical temperature.
