Excellent Tool

This publication reviews recent advances in polarized neutron diffraction (PND) studies of magnetic anisotropy in coordination compounds comprising d or f elements and having different nuclearities. All these studies illustrate the extent to which PND can provide precise and direct information on the relationship between molecular structure and the shape and axes of magnetic anisotropy of the individual metal sites. It makes this experimental technique (PND) an excellent tool to help in the design of molecular-based magnets and especially single-molecule magnets for which strong uniaxial magnetic anisotropy is required.

Superparamagnetic Behaviour

Three mononuclear complexes [CoII(biq)X2] (biq = 2,2′-biquinoline; X = Cl, Br, I) possess a sizable magnetic anisotropy, and they display a superparamagnetic behaviour in an applied external field that culminates between BDC = 0.2–0.3 T.
