Re: Memories and other stories from Pye etc PMR engineers.
Disaccommodation in ferrite cores is quite normal and has to be handled in designing precision ferrite inductors for filters. It can be reset thermally, though the temperatures needed can be somewhat above the capabilities of wire insulation. I'm a bit surprised at a material with a disaccommodation offset trigger-able by the field from a good old TCP1 iron.
The full story is in "Soft Ferrites" by Snelling (Iliffe) which is pretty much THE book on ferrites
