Superconductor world record

A scientists team from Cambridge breaks superconductor world record, that has stood for more than a decade.

The 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.”

They 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.

Professor David Cardwell of Cambridge’s Department of Engineering, who led the research, in collaboration with Boeing and the National High Field Magnet Laboratory at the Florida State University, said:

“The fact that this record has stood for so long shows just how demanding this field really is. There are real potential gains to be had with even small increases in field.

This work could herald the arrival of superconductors in real-world applications. In order to see bulk superconductors applied for everyday use, we need large grains of superconducting material with the required properties that can be manufactured by relatively standard processes.”
