Interaction fields in doped barium ferrite particle powder systems

الملخص EN

The samples examined in this work, were prepared by mixing barium ferrite powder with a nonmagnetic host to get samples with different concentrations.

Measurements of the interaction fields have been made by measuring the minor hysteresis loops.

The interaction fields were studied as a function of the magnetization of the system.

The results show the presence of staking effect in such materials which lead to strong recommendation to consider the short range interaction even for the lowest concentrations.

Also the demagnetization factor was determined for these systems.
