Abstract :
The title compound was recently shown to exhibit a spin-flop transition (SF) from an antiferromagnetic (AF) to a canted AF (CAF) phase. Here, we report on the evolution of the magnetic anisotropy in the AF and CAF phases as measured by cantilever magnetometry. New curvature was found in the AF-CAF phase boundary below 2K, providing evidence that the T=0 ground state may be CAF rather than AF, and that the CAF state is reentrant at low temperature.
