Abstract
⺠Dynamic susceptibility of magnetite nps gives T-dependent K and Ï0 values. ⺠Anisotropy K and prefactor Ï0 are highly correlated. ⺠Fits show Ï0 upper limit is around 0.1 ns at 255-400 K. ⺠Optimal diameter magnetite np for SQUID relaxometry is 25-26.5 nm. ⺠Parameters from susceptibility also model relaxometry results.
