- We have studied the magnetic properties of ZnO nanocrystals doped with Fe$\text{}_{2}$O$\text{}_{3}$ in the magnetic dopant range from 5 to 70 wt%. The nanocrystals were synthesized by wet chemical method. The detailed structural characterization was performed by means of X-ray diffraction and micro-Raman spectroscopy measurements. The results of systematic measurements of magnetic AC susceptibility as a function of temperature and frequency are presented. We observed different types of magnetic behavior. For ZnO samples doped with low content of Fe$\text{}_{2}$O$\text{}_{3}$, the results of low-field AC susceptibility are satisfactorily explained by superparamagnetic model including inter-particle interactions. With the increase of magnetic Fe$\text{}_{2}$O$\text{}_{3}$ content, the spin-glass-like behavior is observed.
