摘要：
The magnetoresistive properties Of Co75Fe25/Ir22Mn78-based top (TSV), bottom (BSV), and dual type spin valves (DSV) by DC magnetron sputtering were investigated. The magnetoresistance (MR) ratio and exchange coupling field (H-ex) of TSV were 5.6% and 430 Oe, respectively. For BSV the H-ex values (1180 Oe) is much higher while MR ratio (3.6%) is reduced with respect to TSV. The blocking temperatures (T-B) of the TSV and BSV were 250degreesC and 270degreesC, respectively. DSV, with MR ratio of 7.8% and H-ex of 850/510 Oe, showed two different exchange loops.
