Abstract
We have addressed the possibility of surface ferromagnetism in (formula presented) by investigating its surface electronic states by angle-resolved photoemission spectroscopy (ARPES). By cleaving samples under different conditions and using various photon energies, we have isolated the surface from the bulk states. A comparison with band structure calculations indicates that the ARPES data are most readily explained by a nonmagnetic (formula presented) surface reconstruction.
