| 摘 要： | 采用离子束溅射技术制备了一系列不同含量x的(Ni0.8Co0．2)x-Ag1-x。颗粒膜样品，并对样品的各向异性磁电阻和巨磁电阻效应进行了研究，在x=0．4的样品中，GMR值达最大值，为-3％，而AMR值在x=0．75时为0．8％。随着NiCo质量分数x的增加，电子输运行为有着一个从GMRAMR的转变。考察其输运性质，试图来更深入地理解各向异性磁电阻和巨磁电阻效应的物理本质。

| Abstract: | A series of (Ni_(0.8)Co_(0.2))_x-Ag_(1-x)nano-granular films has been fabricated on glass substrates by an ion-beam sputtering technique. The anisotropic magnetoresistance and giant magnetoresistance effect of the samples were investigated. The GMR value reaches a maximum of-3%at x=0.4, and the AMR reaches 0.8% at x=(0.75.) A transition from GMR to AMR was observed as x rises. In order to understand deeply the physics essence of the anisotropic magnetoresistance and giant magnetoresistance effect, the transport properties were investigated. |
