Abstract
We have addressed the possibility of surface ferromagnetism in Sr2RuO4 by i nvestigating its surface electronic states by angle-resolved photoemission spectroscopy (ARPES). By cleaving samples under different conditions and us ing various photon energies, we have isolated the surface from the bulk sta tes. A comparison with band structure calculations indicates that the ARPES data are most readily explained by a nonmagnetic root2 x root2 surface rec onstruction.
