Spin dependent transport phenomena in the NiFe/AlO/Cu/AlO/NiFe double tunnel junctions

In this study, in order to develop the highly performable spintronics devices such as three terminal spin devices, we first began to examine the fundamental spin transport properties in the spin-valve type NiFe/AlO/Cu/NiFe/MnIr double junctions, which has never been studied experimentally so far. The samples were grown on SiO/sub 2/ substrate by magnetron sputtering method. Magnetoresistance effects in the NiFe/AlO/Cu/NiFe/MnIr double junctions was studied at 4.2 K and room temperature.
