WebHall Effect Switches and Magnetoresistive sensors provide a digital switching output (or relay output) that activates when a large enough magnetic field is present and deactivates when the magnetic field falls below the sensitivity of the sensor. WebThe magneto-resistive drop was ~0.25% at room temperature and ~ 2.5% at 77 K, with both measured in fields of 6 kOe. In summary, a detailed GMR—Study of the influences of HPT process parameters including deformation temperature and composition on GMR is lacking, which is the motivation for and aim of the presented work. i owe you many thanks
