(a) Photoresponse of a single SnO2 nanowire (NW) device with a bias of 0.1 V exposed to magnetic field strengths of 350, 500, 750 and 1400 G and the illumination of a He—Cd laser working at 325 nm with an excitation intensity of 8 W m−2. (b) The gain logarithmic plot versus illumination intensity of a single SnO2 NW device exposed to magnetic field strengths of 350, 500, 750 and 1400 G.
