Abstract
A high-temperature superconducting magnetic sensor having superconducting layers formed on a substrate, a superconducting quantum interference device (SQUID) being formed on the superconducting layers, the high-temperature superconducting magnetic sensor includes: a pickup coil that is formed on the superconducting layer and is connected to an inductor of the SQUID; and an input coil that is formed on the superconducting layer, is connected to the inductor of the SQUID and the pickup coil to form a closed loop, and is magnetically coupled with the inductor of the SQUID. In planar view, at least one turn of the input coil surrounds the inductor of the SQUID, or is surrounded by the inductor of the SQUID. The width of the superconductor forming the inductor of the SQUID is 10 μm or less.
