Abstract
A method and a structure for a low temperature thermometer is provided. The present invention may include a method of determining an ambient temperature is below a transition temperature, the method including measuring a magnetic field of a magnetic field source, where a superconducting film is positioned between a magnetic field sensor and the magnetic field source, where the superconducting film has the transition temperature, T, based on determining the measured magnetic field approximately equals an expected magnetic field of the magnetic field source, outputting a first state of a switch, wherein the first state of the switch indicates the ambient temperature is above the T, based on determining the measured magnetic field is less than the expected magnetic field, outputting a second state of the switch, where the second state of the switch indicates the ambient temperature is below the T.
