The effect of La3+ ions substitution on the magnetic properties of the composition Li0.5−0.5xZnyLaxFe2.5−0.5x−yO4 (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 La3+-content. The M–H carves showed that the samples are soft ferromagnetic and it can be an excellent candidate for industrial applications.
