Angular dependence of the exchange interaction in fluoride-bridged Gd~Ⅲ-Cr~Ⅲ complexes

摘要

The observed angular variation of the magnetic exchange coupling parameter in a series of fluoride-bridged chromium(Ⅲ)-gadolinium(Ⅲ) complexes is explained by DFT calculations. The relatively new research field of magnetic refrigeration, by means of adiabatic demagnetisation, in paramagnetic, molecular, poly-nuclear, complexes and MOFs has reinvigorated the study of magnetically isotropic, polynuclear d- and f-metal ion compounds.
