關鍵字: | core-shell structure;exchange bias;Fe3O4 nanoparticles;superparamagnetic;magnetic-properties | Project: | Ieee Transactions on Magnetics | 期刊/報告no:: | Ieee Transactions on Magnetics, Volume 41, Issue 10, Page(s) 3397-3399. | 摘要: | Ag nanoparticles; with Fe3O4 shells have been synthesized by the polyol method. The Ag @ Fe3O4 core-shell nanoparticles exhibited a superparamagnetic behavior at the temperature higher than the blocking temperature (100 K) and showed shifted loops under a field cooling process. The enhanced magnetic anisotropy was observed and was ascribed to the surface effect. |
