Auto-ignition synthesis of rare-earth metal-doped Ni–Zn spinel ferrites for electronic applications

A series of Ni0.6Zn0.4Fe2−xLaxO4 (0 ≤ x ≤ 0.10) was synthesized using the sol–gel auto combustion method with metal nitrate to citrate ratio 1:1. The resultant powders were then characterized for their structural morphological compositional and electrical properties. The synthesized powders exhibited a single phase with a spinel structure. TEM, SEM, and DLS evaluation confirmed the fine particle nature of the particles. While the EDAX indicated...
