Additional information

World leading demonstration of the most sensitive, yet lowest noise SQUIDs ever to operate above 4K. These were the first true-nanoSQUIDs to be fabricated that are reproducible, reliable and easy to operate above mK temperatures. Traceable measurements carried out by two NMI's (NPL U.K. and PTB Germany) showing devices to have sensitivities of only two Bohr magneton, whilst simultaneously operating with a noise floor over an order of magnitude better than any other reported device. These devices are now copied in laboratories in the U.S, Australia, Japan, India and Germany.
