چکیده
The temperature and fresuency dependence of tg8 and E' for Nk ~Ztb ferrites was studied in the 10'lo6 Hz frequency range and 20-200°C temperrhrre tange. The experimental curves exhibit aspects very dependent of composition. To verify Ulat interfacial losses, expected to appear in this type of system are compatible with the experimental results a calculation of the dielectric permittivity and dielectric loss wing the Koops' model was made. A good correlation between calculated and experimental curves was found.

We have studied the integration of Ni-Cu-Zn ferrite spinels as well as substituted hexagonal Co2Y-and M-type ferrites into LTCC (Low Temperature Ceramic Co-firing) modules. The cofiring behavior and the magnetic properties of these materials were investigated and evaluated for multilayer applications. Ni-Cu-Zn ferrites exhibit permeabilities of μ = 300 – 500 for operating frequencies in the MHz...
متن کاملTemperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites
The temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites was investigated. Co ions are known to lead to a compensation of the magnetocrystalline anisotropy in Ni-Zn ferrites, at a temperature depending on the cobalt content and the Ni / Zn ratio. We observed similar behaviour in Ni-Zn-Cu and it was found that the core loss goes through a minimum around this magneto-crysta...
