Abstract

Barium ferrite is a permanent magnet that is frequently used in electronic devices such as data storage media, signal absorbers or radar, because of its magnetic properties. In certain uses, it is desirable to have a rod structure to take advantage of the barium ferrite anisotropic properties. In this research, barium ferrite powder with rod structure was made using the sol-gel method using nanocellulose template. Barium ferrite powder was synthesized from a solution of barium nitrate and iron nitrate using the sol-gel method with nanocellulose crystal template with variations in template mass. The structure and properties of barium ferrite were observed using Vibrating Sample Magnetometer (VSM). VSM observations showed the single phase of barium ferrite produces saturation magnetization of 54.6 emu/g, remanence magnetization of 28.6 emu/g. Keywords— Magnetization, Nanocellulose, Nanorod Barium Ferrite.
