摘要
NiO film with similar to 83 nm average thickness is fabricated by sol-gel dip coating technique The sharp switching between low and high conducting states having a large ratio of currents (similar to 10(7)) at low temperature is observed in the NiO film We clearly demonstrate that switching effect can be tuned by controlling external parameters such as magnetic field. thermal excitation, and time duration of the applied voltage Magnetic field induced switching is involved with the extraordinary large magnetoconductance (similar to 98% at 20 K) Large magnetoconductance is significant for the spintronic applications. The resistive switching memory controlled by the external parameters associated with the signature of large magnetoconductance is fascinating for the multifunctional applications.
