Synthesis and characteristic of Li0.35Zn0.3Fe2.35O4 ferrite fiber using filter paper template

• Li0.35Zn0.3Fe2.35O4 fibers were prepared by filter paper template for the first time.
• The formation mechanism of the Li0.35Zn0.3Fe2.35O4 fibers was studied.
• The microwave absorption properties of Li0.35Zn0.3Fe2.35O4 fibers were investigated.

Li0.35Zn0.3Fe2.35O4 crystals fibers were synthesized via sol–gel method using filter paper template. The phase structures and morphologies for the samples were measured. The electromagnetic and microwave absorbing properties of the obtained samples were measured in the frequency ranges of 0.6–18 GHz. The formation mechanism of the Li0.35Zn0.3Fe2.35O4 fibers was studied. Experimental results showed the absorbing bandwidth below −10 dB for Li0.35Zn0.3Fe2.35O4 fibers microwave is superior to that of Li0.35Zn0.3Fe2.35O4 obtained by no template, especially in S and C bands. The detailed microwave absorbing mechanism of the Li0.35Zn0.3Fe2.35O4 fibers was investigated.
