From: Ultrahigh-gain single SnO2 nanowire photodetectors made with ferromagnetic nickel electrodes
Resistance of nanowire (NW) (RNW) plot versus remanence magnetization (mr). RNW is proportional to 
at low mr region, and RNW is proportional tos at high mr region. Inset: the current difference with and without magnetic field (δI) is proportional to 
.
