【Abstract】　In this paper , the progress in the study of magnetoresistance (MR) materials is reviewed and the presently focused four classes of giant magnetoresistance(GMR) materials , particularly the applications of MR materials in information storage and so on. are dis2 cussed. We clearly point out that the key to exploitation and application of MR materials is to increase the room2temperature MR of GMR materials and decrease the external magnetic field.
