Summary

DESCRIPTION OF A MEASUREMENT SYSTEM WHICH USES THE PRINCIPLE OF MEISSNER EFFECT TO DETECT THE TRANSITION TEMPERATURE. THE DESCRIBED METHOD ALLOWS THE STUDY OF VARIOUS SAMPLES IN DIFFERENT FORMS. UNLIKE RESISTIVITY, IT DOES NOT REQUIRE ELECTRICAL CONNECTIONS TO THE SAMPLE. THIS IS VERY HELPFUL, ESPECIALLY WHEN THE SAMPLE CANNOT BE SOLDERED TO THE ELECTRICAL LEADS. HOWEVER, AS A DRAWBACK, ONE HAS TO BE VERY CAREFUL IN INTERPRETING THE RESULTS, SINCE ANY SUPERCONDUCTING IMPURITY WILL ALSO GIVE A SIGNAL WHICH MIGHT BE MISTAKEN FOR BULK SUPERCONDUCTIVITY. J. V.
