Abstract
AbstractThe Corbino disk is used to study magnetoresistance as it eliminates Hall‐voltage interference and allows for direct probing of bulk properties. A laser‐triggered magnetoresistance effect in the Corbino disk of a Cu/SiO2/Si structure is reported. When a laser is applied, the magnetoresistance is greatly improved, by 360 times, under a 635 nm laser and a 2.1T magnetic field. In addition, the effect shows a close connection with the geometry of the nanoscale metal‐film structure. This effect is attributed to an increase in carrier concentration and bending of the motion path under the laser and magnetic field. This work suggests a new approach for the exploration of the magnetoelectric properties of nanoscale metal films and opens a new window on the use of light to adjust magnetoresistance devices.
