Correlating Blocking Temperatures in Single Molecule Magnets with Raman Relaxation

We report a six coordinate DyIII single-molecule magnet
(SMM) with an energy barrier of 1110 K for thermal relaxation of
magnetization. The sample shows no retention of magnetization
even at 2 K and this led us to find a good correlation between the
blocking temperature and the Raman relaxation regime for SMMs.
The key parameter is the relaxation time (𝜏switch) at the point where
the Raman relaxation mechanism becomes more important than
Orbach.
