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 (Co

; 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.
