Abstract:
The latest research progress on giant magnetoresistance materials with tunnel junctions, including the multi-layered films, nano-particulate films and polycrystalline bulk materials that have been developed in recent years, are reviewed on the basis of an overview of the tunnel junction magnetoresistance effect and its mechanism. The types of tunnel junction magnetoresistance materials, chemical compositions, microstructural features, magnetoresistive properties, processing techniques and their potential applications are discussed with regard to their favorability as polycrystalline magnetoresistance materials. The polycrystalline magnetoresistance materials with tunnel junctions prepared by using a simple and low cost preparation technique are investigated in order to gain a breakthrough development.[著者文摘]
