Abstract
The earlier data for the magnetic properties of YBa2Cu3O7 − x polycrystals are used to design a highly sensitive device measuring weak magnetic fields. The sensitivity of the device is close to that of SQUIDs and much higher than the sensitivity of flux-gate meters. At the same time, the device is simpler in design and more reliable in operation than SQUIDs. Unlike SQUIDs, the device makes it possible to directly measure the magnetic field strength, has a wide measuring range, and exhibits a well-defined directional pattern.
