Back Cover: Large Zero-Field Splittings of the Ground Spin State Arising from Antisymmetric Exchange Effects in Heterometallic Triangles (Angew. Chem. Int. Ed. 21/2014)
The antisymmetric component of the electronic exchange interaction (also known as Dzyaloshinski–Moriya exchange) is often overlooked in modeling the magnetic data of molecular species, but in the Communication by E. J. L. McInnes and co-workers on page 5310 ff., it is shown to be responsible for the large magnetic anisotropy in the S=5/2 ground state of a trimetallic complex. The illustration plays on the concept of “antisymmetry” and triangles with an Escher triangle.
