A series of Ni0.6Zn0.4Fe2-xLaxO4 (0 <= x <= 0.10) particles were synthesized using the sol-gel auto combustion method with a metal nitrate to citrate ratio of 1:1. The synthesized particles exhibited a single spinel structure and fine particle nature, with expected stoichiometric cation ratios confirmed by EDAX. These samples showed increased electrical conductivity, high dielectric constant, low dielectric losses, high saturation magnetization, and low coercivity, making them potential candidates for high-frequency 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 the samples were having the expected stoichiometric cation ratios. An increase in electrical conductivity, high dielectric constant, and low dielectric losses in combination with high saturation magnetization, low coercivity, observed in the present samples make them prospective candidates for high-frequency electronic applications like inductance/transformer cores, antennas, and microwave absorbers.
