摘要：Single phase Ni0.5Zn0.5 Fe2O4 and Ni0.5Zn0.5Fe2O4/PAA compound nano particles were prepared by boiling and refluxing method, and allowed self-assemble into one dimensional nanowire induced by alternating magnetic field. Room temperature hysteresis loop shows that saturation magnetization and coercive force of Ni0.5Zn0.5Fe2O4 particles coating with PAA decrease to 21.1 emu/g and 3.2 Oe, respectively. Polarizing microscope images show that prepared soft magnetic ferrite compound particles respond to applied magnetic field with magnetic flux density of 0.05 T sensitively because of self-strengthener of magnetic template by alternating magnetic field and form into one dimensional nanowire. From SEM images, nanowires are structured by small agglomerated nano compound head by tail whose diameter is 200 nm and aspect ratio is higher than 100.
