Abstract

Angular-dependent magnetoresistance characteristics in Si(001)/NiO(300A)/NiFe(tequals450, 1000, 1350A) thin films was investigated in terms of an angle between current and applied magnetic field. The samples were grown by RF-sputtering and DC-sputtering methods on naturally oxidised Si(001) substrates. First, NiO layer(300A) was grown on Si substrate, followed by the deposition of NiFe layers as a function of NiFe thickness under the condition of in-situ magnetic bias-field of approximately 500G. The measurement of angular magnetoresistance in Si(001)/NiO(300A)NiFe(tequals450, 1000, 1350A) thin films were carried out in variation of an angle between current direction and external magnetic field. Also, on the base of single magnetic domain model, the comparison between the measured and the calculated MR profiles was made. For t_NiFe equals 450A, symmetrical MR characteristics were observed as sweeping external magnetic field proceed. However, for t_NiFe equals 1000A, asymmetric MR profiles were shown.
