The theory of transverse, longitudinal and paramagnons is developed within the many-electron operator spinors (MEOS) representation. They appear as excitations of a spin part of ferromagnetic (FM) metal covalent interactions. The interaction of transverse FM magnons with chemical bonds fluctuations (CBF) within the MEOS form renormalizes their exchange-coupling hardness by the term Delta D proportional to root T. Such a correction dominates near the f.c.c.-b.c.c. transformation (x congruent to 1/3, in invar, ...). The linear spectra of longitudinal (T < T-c) and paramagnons (T > T-c) depend strongly on temperature, T. In contrast to diamond (with forbidden band E-g congruent to eV), the weaker covalent C-0-C+ bond in graphene (G) leads to a linear spectrum of charge carriers, E-k(p, n) = -/+ v(p,n)k (at E-g -> 0 eV). The Hall effect caused by antisymmetry of the spin and orbital parts of C+-C+ bond depends strongly on T in a weak semiconductor (s/c) G. The Hall electromotive force, U-H(T, M), is defined by the Permalloy (Py) layer magnetization within the G/Py superlattice (on the G strip). The U-H(T, M, t) dynamics is described, when the Bloch (B) or Neel (N) domain walls are parallel to the J(y) current within the s/c G strip and move (x = v(B,N)t).
