| Abstract |
| Synthesis of nanosized nickel ferrite by a template method where tartaric acid is used as a ligand and
nitric acid as an oxidant is described. The synthesized powders were characterized by TGA, XRD, FTIR,
TEM, BET, VSM and SQUID studies. The average crystallite size of the phase pure material was of 30 nm
and the surface area was found to be 20.37 m 2 .g –1 . Magnetic measurements of the phase pure powder
were carried out at room temperature by VSM at a magnetic field of 1 Tesla, and by SQUID at a magnetic
field of 6 Tesla. High saturation magnetization of 31.43 emu.g –1 is observed in case of VSM and 43.36
emu.g –1 is observed for SQUID measurements. Comparative analysis of MS values synthesized by
different routes are compared. |
