We investigate the correlation between the change of magnetic properties and structural transition for Fe-based alloy (Fe1-xNix, Fe1-xCox, and Fe1-xVx) films, which were grown on W(110) substrate. To clarify the correlation clearly among the electronic structure, magnetic properties, and structural transition as a function of alloy composition, we performed the spin-summed and resolved photoemission spectra (SSRPES) and low energy electron diffraction (LEED).
