A comparison of the effects of symmetry and magnetoanisotropy on paramagnetic relaxation in related dysprosium single ion magnets

Abstract

Dysprosium complexes of the tmtaa2− ligand were synthesized and characterized by X-band EPR and magnetism studies. Both complexes demonstrate magnetoanisotropy and slow paramagnetic relaxation. Comparison of these compounds with the seminal phthalocyanine complex [Dy(Pc)2] shows the azaannulide complexes are more susceptible to relaxation through non-thermal pathways.
