Description
Highlights: ► Magnetoresistance (MR) in Ni80Fe20-ITO granular film are investigated. ► MR is positive at high temperature, and is negative at low temperature. ► MR results from the competition among three mechanisms. - Abstract: The magnetic properties, electrical properties and magnetoresistance are investigated in Ni80Fe20-ITO granular film with various volume fractions VNF of Ni80Fe20. The room temperature magnetization hysteresis of sample with VNF = 25% shows superparamagnetic behavior. Current-voltage curve of sample with VNF = 25% at 175 K shows typical tunneling-type behavior. The magnetoresistances of samples with low VNF are positive at high temperature, and are negative at low temperature. The temperature-dependent magnetoresistances result from the competition among ordinary magnetoresistances, the granular-typed tunneling magnetoresistance and the spin-mixing induced magnetoresistances.
