Magnetoresistance Effect in NiFe/BP/NiFe Vertical Spin Valve Devices

Figure 2

Characterizations of NiFe/BP/NiFe spin valve device. (a) The current-voltage curves of device at different temperature from 4 K to 300 K and resistance curve as a function of temperature at zero magnetic field in inset figure (a). (b) Resistance curves of device when external magnetic field is applied at 300 K and the value of MR is 0.23% for the structure of Py/BP/Py spin valve.
