Initial permeability and dc conductivity of cu- zn ferrite

الملخص EN

The initial permeability and dc conductivity as a function of temperature ranges from 300 K to 800 K are measured for Cu1-sZnsFe2O4 compounds.

This compound was prepared using the conventional ceramic double sintering process with various compositions.

The results show a drop at the Curie temperature.

The relation of log (ðT) against 103 / T illustrates a transition near Curie temperature.

The activation energy in the ferromagnetic region is found in general to be less than that in paramagnetic region.

An attempt is also made to explain the conduction mechanism in these ferrites.
