Substitution effects on magnetic properties of Mg1.3-xMnxAlyFe1.8-yO4 ferrite

AIP Advances, 2017
Mg1.3-xMnxAlyFe1.8-yO4 (x = 0.1–0.2, y = 0.15–0.3) spinel ferrites were prepared using conventional ceramic technique. Highly densified Mg–Mn–Al ferrites (with 99% theoretical density) were obtained, and the influence of Mn and Al substitution on the ...

Temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites

, 2010
The temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites was investigated. Co2+ ions are known to lead to a compensation of the magneto-crystalline anisotropy in Ni-Zn ferrites, at a temperature depending on the cobalt content and ...
