Abstract

Multifrequency (24-94 GHz) and variable temperature (5-300 K) single-crystal electron paramagnetic resonance (EPR) studies have been used to probe the magnetic exchange pathway, spin dynamics, and assignment of the principal magnetic axes in the organic molecular magnet 4-(4'-cyano-tetrafluorophenyl),1,2,3,5-dithiadiazolyl, beta-p-NCC6F4CNSSN. Orientation-dependent studies indicate that the dominant exchange pathway is perpendicular to the crystallographic c-axis, while variable-temperature studies confirm the ordering transition at 36 K and illustrate that the sublattice magnetization is essentially saturated below 15 K. The orientation dependence of the EPR spectra at 5 K has confirmed the easy axis of magnetization to be parallel to the b-axis and allowed the first determination of the intermediate and hard axes of magnetization as parallel to c- and a-axes, respectively.
