多齿配体双三丙烷{(CH2OH)(3)CNH-(CH2)(3)NHC(CH2OH)(3)}与Ln(NO3)(3)-6H(2)O和Fe3O前驱体反应生成了一系列Fe(6)Ln(2)纳米团簇。磁测量表明，Fe-6磁芯表现出亚铁磁性，而Fe6Dy2和Fe6Tb2则表现出缓慢的磁弛豫。
The reaction of polydentate ligand Bis-tris propane {(CH2OH)(3)CNH-(CH2)(3)NHC(CH2OH)(3)} with Ln(NO3)(3)-6H(2)O and Fe3O precursor resulted in the formation of a series of Fe(6)Ln(2) nanoclusters. Magnetic measurements indicate that the Fe-6 core exhibits ferrimagnetic behavior, and slow magnetic relaxation was observed in Fe6Dy2 and Fe6Tb2.
