摘要: In this work, the magnetic resonance (MR) of Fe3O4, ZnFe2O4, and NiFe2O4 is measured in order to investigate the doping effects of Zn and Ni. Our results clearly demonstrate a distinct difference in the dynamic behaviors of resonance field and resonance linewidth among these three samples. Based on the data of g-factor vs. temperature, the magnetic coupling in Fe3O4 and NiFe2O4 is much larger than that of ZnFe2O4. Furthermore, the MR spectrum of ZnFe2O4 splits into two lines above 170 K. The possible mechanism causing the dramatically different patterns of magnetic phases in these samples is discussed.
