Latest Patents
Frank J. Adrain holds a patent for a novel technique using magnetic field dependent phase detection. The invention relates to a method and apparatus designed to detect the superconductive state by measuring the change in the resistance of a sample. A direct current (dc) magnetic field is imposed on the sample while the temperature is swept. The strength of the magnetic field is maintained below the critical value and is frequency modulated by the application of an alternating current (ac) field, ensuring that the total magnetic field remains positive. The resistance of the sample is measured incrementally as the temperature is adjusted, and phase detection occurs at the modulation frequency. This method identifies a composition as superconductive by demonstrating a precipitous drop in resistance due to magnetic field dependent changes.
