Giant coercivity of dense nanostructured spark plasma sintered barium hexaferrite
Frederic Mazaleyrat, Alexander Pasko, Andras Bartok +1
Due to the limited rare-earth elements resources, ferrite magnets need to be improved drastically. Ideally, for a true hard magnet, the coercive field should be larger than the sat…
Analysis of volume distribution of power loss in ferrite cores
Martino Lobue, Vincent Loyau, Frédéric Mazaleyrat
We present a technique to estimate the inhomogeneities of magnetic loss across the section of ferrite cores under ac excitation. The technique is based on two distinct calorimetric…
Temperature dependence of spin resonance in cobalt substituted NiZnCu ferrites
Frederic Mazaleyrat, Antony Lucas, Eric Labouré +1
Cobalt substitutions were investigated in Ni0.4Zn0.4Cu0.2Fe2O4 ferrites, initial complex permeability was then measured from 1 MHz to 1 GHz. It appears that cobalt substitution led…
Temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites
Frederic Mazaleyrat, Richard Lebourgeois, Eric Labouré +1
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 anisotrop…
