Abstract

Aim

A series of nickel doped cobalt (NiCoFeO, x=0.0 to 1.0) were successfully synthesized using green synthesized process.

Methods

Tensile strain of all positive slope samples observed from the W-H (Williamson Hall) plot. It was discovered that as Ni-substitution increased, the dielectric constant (є’) increased from 148.07 to 243.62. Conversely, when the amount of Ni-substitution increases, the dielectric loss (tan δ from 0.23 to 0.05), imaginary part (є” from 98.81 to 17.87), and ac conductivity (σ from 1.62 to 0.15) all decreases at 1MHz frequency.

Results

This demonstrates that when Ni-substitution increases, energy losses at high frequencies decrease. Dielectric constant and ac conductivity, of all samples act in accordance with Koop's theory, the Maxwell-Wagner polarization procedure, and electron hopping.

Conclusion

This makes them suitable materials for high-frequency applications.
