Uncertainty Estimates for Magnetic Relaxation Times and Magnetic Relaxation Parameters
2019-07-15T16:22:51Z (GMT) by
We describe a method for obtaining uncertainties in magnetic relaxation times from AC susceptibility experiments. We provide a program for fitting AC data and the resulting magnetic relaxation times accounting for the uncertainties correctly, to give magnetic relaxation parameters with accurate uncertainties. We show that the implicit distributions in the magnetic relaxation times have large consequences for the uncertainties in the model parameters, and that the magnitude of these uncertainties appear to correlate with crystallographic disorder in three families of high-performance Dy(III) single-molecule magnets.
