The Mn1-xZnxFe2O4 (x = 0.46, 0.47, 0.48, 0.50, 0.51) ferrite materials were prepared by solid-state reaction. The effects ofvarying Zn concentration on the magnetic characteristics and microstructure of MnZn ferrites were investigated. All of theseferrites are one spinel phase, according to XRD analysis, and no additional heterogeneous phases are generated. Thediffraction peaks of the samples appear to be shifted to a higher angle compared to the standard cards. The sample's very bigand irregular grain development caused the sample's grain size to vary as the zinc level increased. The power loss of MnZnferrite can be decreased because to this phenomena. The PCV value decreases as the Zn level of the samples increases. The PCVof this ferrite is as high as 242.6 mW/cm3 at a frequency of 150 kHz with a Zn concentration of x = 0.46. Under the same testcircumstances, ferrite's PCV value is only 115.2mW/cm3 when the Zn concentration is x = 0.48. The complex permeability ofthe samples rises with an increase in Zn concentration. In the ferrite sample with the highest Zn content (x = 0.51), its μ' valuekeeps at a high level with the change of frequency. When the frequency is 10 kHz, the μ' value is as high as 260.9. Additionally,all of these ferrite samples demonstrated stability against interference at frequencies lower than 150 kHz.
Abstract
The Mn1-xZnxFe2O4 (x = 0.46, 0.47, 0.48, 0.50, 0.51) ferrite materials were prepared by solid-state reaction. The effects ofvarying Zn concentration on the magnetic characteristics and microstructure of MnZn ferrites were investigated. All of theseferrites are one spinel phase, according to XRD analysis, and no additional heterogeneous phases are generated. Thediffraction peaks of the samples appear to be shifted to a higher angle compared to the standard cards. The sample's very bigand irregular grain development caused the sample's grain size to vary as the zinc level increased. The power loss of MnZnferrite can be decreased because to this phenomena. The PCV value decreases as the Zn level of the samples increases. The PCVof this ferrite is as high as 242.6 mW/cm3 at a frequency of 150 kHz with a Zn concentration of x = 0.46. Under the same testcircumstances, ferrite's PCV value is only 115.2mW/cm3 when the Zn concentration is x = 0.48. The complex permeability ofthe samples rises with an increase in Zn concentration. In the ferrite sample with the highest Zn content (x = 0.51), its μ' valuekeeps at a high level with the change of frequency. When the frequency is 10 kHz, the μ' value is as high as 260.9. Additionally,all of these ferrite samples demonstrated stability against interference at frequencies lower than 150 kHz.
