摘要： In this note, a new approach is adopted to the magnetism in metallic hydrogen, i.e., based on the Kim theory and Stoner model the electron-phonon interaction is introduced into the itinerant electron mag-netism theory. A calculation of spontaneous magnetization of metallic hydrogen at T=0 K shows that in spite of no change in the para- to ferro-magnetism value, rsc of W-S radius rs, the spontaneous magnetic moment of electron in ferromagnetic state, where rs>>rsc, is considerably reduced by lattice vibrations.
