摘要：

Two's company: Coupling two Dy3 triangles to give Dy6 (see picture; Dy blue, Cl green, O red) leads to a dramatic enhancement of the barrier height to magnetization reversal. The enhancement has been rationalized by single-crystal magnetometry measurements and ab initio calculations. Copyright © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
