Spin Hall Effect Device For Magnetic Sensor Application
2018 CONFERENCE ON PRECISION ELECTROMAGNETIC MEASUREMENTS (CPEM 2018)(2018)
Abstract
In this paper, the spin Hall device was fabricated to magnetic sensor applications. This device based on the spin Hall effect by observing in ferromagnetic and heavy metal multi-layer structures. We measured shift of switching current with changing a z-component of small magnetic field through anomalous Hall effect measurement. The shift of switching current can be applied the magnetic sensor. Also, we controlled the sensitivity of this device changing efficiency of spin Hall effect. This device is a good candidate for magnetic sensor to measure a wide dynamic range of magnetic field.
