The study of holmium substituted spinel ferrites for high frequency applications

Abstract

The spinel ferrites are famous due to their unique electrical and magnetic performance. The current inspection is about the electrical and magnetic features of Holmium (Ho) substituted Co-Zn-ferrites (Co0.6Zn0.4Ho x Fe2−xO4; where x = 0.0 and 0.1). The Single-phase cubic configuration of prepared ferrites was perceived from X-ray diffraction data. The substituted sample has one order larger direct current (dc) resistivity as compared to the un-substituted sample. The substitution of Holmium decreased dielectric loss significantly. The dielectric study of samples was completed within the frequency range of 0.1–20 MHz. The comparison of dielectric parameters for different temperature values was measured. The magnetic characterization was done within the applied field of 2 kOe. The evaluated properties of samples like larger dc resistivity and less dielectric loss showed that the materials can be utilized in high-frequency applications.
