| 中文摘要 | This paper reports that the homogeneous nanocrystalline LCMO(core)/SFMO(shell) and SFMO(core)/LCMO(shell) series composites are successively synthesized using polymer-network sol-gel method. With the increase of SFMO content in the composites, the remanence magnetization M-r increases while the coercivity H-c decreases. This fact indicates that the ferromagnetic phase boosts up. Moreover, the LFMR (1 T) of the composites succeeds the preponderances of both SFMO and LCMO; i.e., the magnetoresistance (MR) value increases from 300 to 5 K and keeps a high level. In particular, the MR value of the LS-8 composite reaches 55% at 5 K and 7 T. |
