文摘

In this paper, a series of Co-substituted Mn-Zn ferrites with the formula Co_xMn_0.8-xZn_0.2Fe₂O₄ (x = 0, 0.2, 0.4, 0.6 and 0.8) have been successfully obtained by ultrasonic-assisted ball milling approach. The characterization of the samples has been done by using room temperature X-ray diffraction (XRD), transmission electron microscopy (TEM), vibrating sample magnetometry (VSM). The XRD results reveal that the formation of single-phrase ferrite fully is completed after 60 h. The TEM analysis confirms that the average size of nanoparticles is about 25–30 nm. A maximum saturation magnetization of 78.7 emu/g is obtained when x = 0.6, which decreases with further Co doping. The changes in fluorescence intensity and conductivity reflect the reaction speed and confirm the coupling effect of ultrasonic and ball milling.KeywordsCo_xMn_0.8−xZn_0.2Fe₂O₄UltrasonicBall milling
