We have fabricated a p-Si/Zn 0.3 Ni 0.7 Fe 2 O 4 (ZNFO)/CuPc/Au heterostructure and investigated its magnetic field-induced tuning of photocurrent.Under illumination of 660nm laser,photocurrent increases with increase of optical power.With simultaneous application of light and magnetic field, a drastic change in the ratio of photocurrent with magnetic field (I(H)) to photocurrent without magnetic field (I(0)) is observed for optical power variations at a fixed positive bias.A significant decrease in electrical hysteresis width (|ΔI|) with magnetic field at higher optical illumination is noticed.
