Does Neutron Radiation affect Ferrite/Ceramic Magnets?
(OP)
Does anybody know if neutron bombardment of Ferrite/Ceramic permanent magnetic material will cause any irreversible/irrecoverable loss in the magnetic field. If so why?

If you have trouble finding the information you could try the U of Dayton magnetics department or the Air Force materials group at Wright Patterson (also in Dayton OH).
I don't remember. Some materials were damaged and some were not.

A few months ago I came across a paper by a group at Fermi National Acccelerator Lab. They exposed strontium ferrite magnets (Ceramic 8) to proton & gamma radiation. They only noticed normal thermal flucuations.
Moskowitz's book reports a lowered remanence after exposing Barium ferrite/ceramic (not used much nowadays) magnets to over 10e19 neutrons and 275degC. He doesn't quantify the amount of loss. However, given that temperature, I suspect most of the loss was due to thermal effects.
The link for the Fermilab report is:

I recommend pasting the complete text of that link into the address field of your browser. I just tried it that way in it works.

but i am not sure. what i mentioned have to do with pure physics theory but not with real life problems
