3. HTS CONCENTRATOR
- Top and side views of the high temperature superconducting (HTS) concentrator, the blue rectangle represents the location of the GMR sensor;
- The calculated magnetic field (color map) produced by the Meissner currents above the superconducting constriction is represented below;
- The relations used for the magnetic field calculations are also given.
|
- An vortex pinning method was investigated for the HTS films in order to reduce the thermal noise of the HTS constriction and improve the overall noise characteristic of the hybrid sensor;
- The proposed method involves the use of nanometric (150 nm) cobalt dots deposited on top of the HTS film (see Scientific Report);
