Journal of Magnetism and Magnetic Materials 272-276 (SUPPL. 1) : e1801-e1803. ScholarBank@NUS Repository. https://doi.org/10.1016/j.jmmm.2003.12.864 | Abstract: | K2NiFe3.5V3.5O16 with the hollandite structure was prepared by conventional ceramic method. The specimen exhibited the ferrimagnetic behaviour with a relatively high Curie temperature of approximately 870 K and a room temperature saturation magnetization of ∼ 15 emu/g. A maximum of magnetization appeared at 120-150 K and a relatively abrupt decrease in magnetization was detected below 100 K, accompanied by a change of slope in temperature-dependent resistance. The Mössbauer spectra could be well fitted with two sextets in the temperature range of 78-290 K. A change in average hyperfine field and chemical shift was observed below 150 K. © 2003 Elsevier B.V.
