At the University of Basel, physicists have designed a compact instrument capable of detecting very small magnetic fields.
(a) A conventional superconducting quantum interference device (SQUID) consists of a superconducting ring interrupted at two points by weak links (in this case a graphene layer). (b) The new SQUID is made up of a stack of two-dimensional materials, including two graphene layers separated by a thin film of boron nitride. Image Credit: University…
