摘      要：Magnetometers based on superconducting quantum interference devices (SQUIDs), fabricated from thin films of YBa2Cu3O7-x and operated in liquid nitrogen at 77K, have achieved a magnetic field noise below 10 fT Hz(-1/2). These devices are now sufficiently sensitive for use in an intriguing variety of applications, including geophysics, magnetocardiology, nondestructive evaluation of metal structures, and scanning SQUID microscopes.
