ABSTRACT:
A superconductive magneto-resistive device is made up of superconductive materials having grain boundaries which act as weak couplings. The superconductive material will change from the superconductive state to the normal state when a magnetic field is applied to the material. The superconductive material can be used in various devices for measuring.
