摘要：
The magnetoresistance of [Co/M/ Fe3O4](M = Pt, Cu, TiN) trilayer films has been investigated. The high-quality Fe3O4 film prepared by the magnetron spattering method using Ar - H-2 gas has been used. The GMR effect has been observed only for [Co/Cu/ Fe3O4]. The GMR values are 0.1% and 0.7% at RT and 4.2 K, respectively. The magnetoresistance effect for trilayers using Fe3O4 film is discussed, considering the current ratio among three layers. (C) 2003 Elsevier B. V. All rights reserved.
