Spintronic devices, such as giant magnetoresistance and tunnel magnetoresistance (TMR), provide magnetic sensors for various applications with large markets. This talk will present our recent studies on magnetic sensors using TMR and anomalous Hall effect (AHE). First, after a brief introduction on the previous studies on TMR sensors, our unique strategy to obtain TMR sensors without magnetic hysteresis is described. Using these sensors, we have investigated the low-frequency 1/f noise of the sensor devices. The second topic is AHE. The giant AHE discovered in ferromagnetic and antiferromagnetic materials with topological electronic structures is of great fundamental interest. We emphasize that such giant AHE has a great potential for practical application for read head sensor for future HDDs and other novel magnetic sensors.
