Rapid testing for superconducting
Inspector Hall is designed specifically for laboratories developing thin film superconducting materials. The sample sits in a liquid nitrogen bath between a DC electrical excitation coil and a high performance magnetic field sensor. When below the superconducting transition temperature, Tc the sample partially shields the sensor from the magnetic field of the coil. As the liquid nitrogen evaporates, the sample warms and passes through Tc and thus more magnetic flux from the coil reaches the sensor. The change in magnetic flux is related to the product of superconducting critical current density Jc and the superconducting film thickness. The sensor reading therefore provides a fast comparative measure between samples of the degree of superconductivity in your samples and also a value for Tc.
