Abstract

The effect of La<sup>3+</sup> ions substitution on the magnetic properties of the composition Li<inf>0.5-0.5x</inf>Zn<inf>y</inf>La<inf>x</inf>Fe <inf>2.5-0.5x-y</inf>O<inf>4</inf> (0.02 ≤ x ≤ 0.1; y = 0.6) was studied. The structure of the samples was investigated using X-ray, SEM and IR. Both of zero field cooled (ZFC) and field cooled (FC) modes magnetization were studied at low temperature range (2 K ≤ T ≤ 400 K). Magnetization applied field-dependence (M-H) curves were measured at low temperature (5 K). The experimental data revealed that the samples exhibited a phase transition from ferrimagnetic state at low temperature to paramagnetic state at high temperature (400 K). The obtained Curie temperature was shifted to lower value with La <sup>3+</sup>-content. The M-H carves showed that the samples are soft ferromagnetic and it can be an excellent candidate for industrial applications. © 2013 Brazilian Metallurgical, Materials and Mining Association.
