| Abstract: | Carbon nanotube coated with manganese zinc ferrite nanospheres was synthesized by the hydrothermal synthesis method at 160℃ and 220℃ for 5h,respectively.An X-ray powder diffraction（XRD）,a transmission electron microscope and a vibrating sample magnetometer（VSM） were adopted for the characterization of the samples.The manganese zinc ferrite is round and the diameter is about 13 nm.Magnetic hysteresis loops showed that the saturated magnetization,remanence and coercivity of carbon nanotube coated with manganese zinc ferrite nanospheres are 10.92 emu/g,4.25 emu/g and 381.43 Oe,respectively. |
