Duncan ,
Something for you.
Here are my thoughts when I started building my device in the summer last year, which very closely resembles both Tiger and stiveip team devices.
In essence it is something not very well known but I figured it out by common sense and from Floyd Sweet papers.
Every atomic particle has spin : electron has ,proton has, neutron too. We are using electron spin and spin of total atom in NMR and ESR , but not spin of nucleus alone. Yes,we can! Here is my theory : iron atoms are like small top, they orientate in external magnetic field in the way which do not oppose it and allow to pass magnetic flux by unpaired electron spin. The only possible way seem to nucleus spin being zero and this is correct for ferromagnetics as I see (I haven't checked it deeply however). I concluded that nucleus spin must also give nucleus magnetic momentum and this spin must be somehow independent of electrons spin which means it probably occur perpendicular to electrons shell spinning somehow.
My question was : what would happen if we flip nucleus spin (from zero state to activated and again to zero)? I imagined such situation: iron atom like a child top swirling in one direction and this rotation being electrons spin, but inside we have a core rotating perpendicular seen from afar like solid.When we flip nucleus spin - it's like having child top glued to some plate and we move that plate.For example this plate is now hanging on ceiling (due to 180 degrees flip). Effectively not much changed ONLY APPARENT rotation direction of electrons spin. Apparent because that didn't required any force on electrons and any change ! We are not stopping electrons ! We are orientating whole atom in space by keeping by nucleus and turning around. Al atoms chains will flip with miniscule energy required, and thus we can flip whole domain easily but the source is this spin flipping action of nucleus.
You can see if that works (and I'm sure it can) we would have magnetic field flip poles in almost no time (and without much force) because of apparent flip of unpaired electrons spin which I believe is the cause of high magnetic permeability of ferromagnetics.
This theoretical effect is something else then normal NMR, it is a spin-off from NMR.
I call it Sweet Effect. in honor of Floyd Sweet. Maybe it has other name but surely it is not very known. It is possibly the source of ferroresonance.
More later if anybody is interested....
