The magnetic transport properties -- magnetoresistive (MR) effects of MnNi/Co/Ag(Cu)/\break Py pinned spin valve structures (SVs) prepared by rf sputtering method and annealed at \(T_{a} = 100\)°C - 500°C for 30 minutes in high vacuum (\(\sim 10^{ - 5}\) torr) are investigated. The received results show a change in the observed MR behaviors from a normal giant magnetoresistance effect to an inverse magnetoresistance effect after annealing at high temperatures, 300°C and 400°C, for these SVs. The origin and mechanism of the IMR behavior are analyzed and discussed. These results will suggest an ability to manufacture SV devices used the IMR effect for enhancing the application capacities for SV-sensor systems.

“…Giant magnetoresistance (GMR) structure was first proposed by Baibich, et al in 1988 [1]. Since then, different micro-sized GMR structures composed of multilayer GMR such as Fe/Cr, CoFe/Cu and Co/Cu, and spin valve GMR such as IrMn/CoFe/Cu/NiFe and PtMn/CoFe/Cu/CoFe, have been extensively studied [2][3][4][5][6][7][8][9][10][11]. Generally speaking, the GMR structures can be used to detect the magnetic field, magnetization reversal and magnetic domain structure and they are able to explain the relevant problems of spins.…”

“…Nowadays, giant magnetoresistance (GMR) devices are playing an increasingly important role in bio-medical assays [12][13][14][15], electrical systems [16][17][18], automotive electronics [19][20][21][22] and read heads [23,24]. In particular, GMRs have been attracting a lot of researchers' interest for their applications in biosensors and biochips due to their high sensitivity, scalability and no interference of the background magnetic signal [2][3][4][5]25,26]. They can be used to detect magnetic signals and biomass signals such as the enzyme, protein, antigen and antibody by labeling the analytes with magnetic particles and detecting the magnetic fringing fields of the particle labels [27].…”
