The research demonstrates the potential of high-temperature superconductors for applications in a range of fields, including flywheels for energy storage, ‘magnetic separators’, which can be used in mineral refinement and pollution control, and in high-speed levitating monorail trains.

New record for a trapped field in a superconductor, beating a record that has stood for more than a decade, could herald the arrival of materials in a broad range of fields. 

A world record that has stood for more than a decade has been broken by a team led by University of Cambridge engineers, harnessing the equivalent of three tonnes of force inside a golf ball-sized sample of material that is normally as brittle as fine china.

The Cambridge researchers managed to ‘trap’ a magnetic field with a strength of 17.6 Tesla – roughly 100 times stronger than the field generated by a typical fridge magnet – in a high temperature gadolinium barium copper oxide (GdBCO) superconductor, beating the previous record by 0.4 Tesla. The results are published today in the journal Superconductor Science and Technology.
