We found that Ru(bpy)2(NH2-phen)2+ and the resulting Ru@CNT and Ru@HOPG exhibited magnetism as exposed to the 473-nm light at room temperature. In view of the fact that most metal-coated magnetic-mode AFM (MFM) tips are prone to oxidation in the air, we then devoted efforts to modifying Ru(bpy)2(NH2-phen)2+ on commercial silicon-based tips to fabricate photomagnetic AFM tips. The resultant tips show application potential in MFM imaging.22’-二吡啶-5-胺基菲繞啉釕化合物多壁奈米碳管磁性原子力顯微術光磁轉換Ru(bpy)2(NH2-phen)2+multi-walled carbon nanotubephotomagnetic
