Abstract
► Coupling of an ultrafast electromagnetic field with the electron spin is investigated using a first-principles approach. ► May be involved in the coherent laser-induced demagnetization of ferromagnetic materials. ► A general expression of the direct spin-field electronic Hamiltonian is postulated.
