Abstract

Two Dy^III ions can be water bridged to form a textbook example of ferromagnetic short-bridged Dy-dimers where strong Ising anisotropy can be evidenced by single-crystal rotating magnetometry. The dimers present both single ion and single molecule magnet behaviour. Magnetic dilution evidences the influence of the ferromagnetic coupling on magnetic relaxation and especially quantum tunnelling.
