Ytterbium can relax slowly too: A field-induced Yb _2 single-molecule magnet

摘要

An unusual dinuclear Yb _2 complex isolated using a mixed ligand strategy leads to field-induced SMM behaviour. Low magnetic axiality and a large tunnelling gap lead to significant quantum tunnelling of the magnetisation, which was reduced under an applied static optimum field of 1600 Oe.
