how does the exchange coupling mechanism work that produce the ferromagnetic properties of materials?

The standard method is that spin alignment forces the spatial part of the multiparticle wavefunction to be antisymmetric. In particular, there is now a reduced probability of having the particles at the same spatial point, thus lowering the Coulomb repulsion.

how much must I know about the strong and weak nuclear force to adequately derive the schrodinger equation using maxwell's equations and QED?

nothing. but your post seems completely off topic.

are you telling me QED and quantum mechanics has nothing to do with the exchange coupling mechanism???

no, I'm telling you that you need to know nothing about the strong and weak force to do what you want to do... which is what you asked.
