摘要

Herein, Zn_0.98-xMn_0.02Tb_xO (x = 3%, 5%) nanocrystals with wurtzite hexagonal structure and average crystallite size of 25–27 nm were prepared by the sol–gel process, those exhibit ferromagnetism (FM) at room temperature. Morphological studies show that the fine nanocrystals are separated by grain boundaries. The photoluminescence spectra show that Tb/Mn co-doping induced various intrinsic defects in these nanocrystals. The dielectric properties were measured at room temperature as a function of frequency. The underlying origin of the observed FM and dielectric behavior was investigated.
