Motivated by neutron scattering experiments in the high-$T_c$ cuprates, wepropose the two-component spin-fermion model as a minimal phenomenologicalmodel which has both local spins and itinerant fermions as independent degreesof freedom. Our calculations of the dynamic spin correlation function provide asuccessful description of the puzzling neutron experiment data and show that:(1) the upward dispersion branch of magnetic excitations is mostly due to thelocal spin excitations; (2) the downward dispersion branch is from collectiveparticle-hole excitations of fermions; and (3) the resonance mode is a mixtureof both degrees of freedom. Using the same model with the same set ofparameters we calculated the renormalized quasiparticle dispersion andsuccessfully reproduced one of the key features of the angle resolvedphotoemission spectroscopy (ARPES) experiments, i.e., the high energy kinkstructure in the fermion quasiparticle dispersion, hence further support thetwo component spin-fermion phenomenology.
