Evidence for Large Antisymmetric Superexchange in Tetrameric Copper Complexes
Evidence for Large Antisymmetric Superexchange in Tetrameric Copper Complexes is a scholarly work, published in 1972 in ''Physical Review Letters''. The main subjects of the publication include ion, crystallography, anisotropy, physics, stock order, antisymmetric relation, Cluster, single-molecule magnet, Superexchange, symmetry, quantum spin liquid, spin, degenerate energy level, copper, skyrmion, and condensed matter physics. The authors illustrate by presenting evidence indicating strongly that the tetrameric copper complex ${\mathrm{Cu}}_{4}$O${{\mathrm{Cl}}_{6}{\mathrm{O}\mathrm{P}({\mathrm{C}}_{6}{\mathrm{H}}_{5})}_{3}}_{4}$ provides the first example in the literature of large (lowest-order) antisymmetric superexchange between orbitally degenerate magnetic ions.
