| Abstract: | In this paper,we emphatically introduce the present situation and development of the different types of giant magnetoresistance effect about magnetic multiplayer film,granular film,perovskite-type oxide and ferromagnetics film tunnel junction. In addition, we briefly describe the mechanism of giant magnetoresistance effect and the application of magnetic sensor,random memory and high-density read head. We also relate the preparation of these materials,and enumerate ten kinds of giant magnetoresistance material. Finally, we emphasize the difference between colossal magnetoresistance and giant magnetoresistance. |
