Surface electronic structure of Sr2RuO4
arXiv:cond-mat/0105487 · doi:10.1103/PhysRevB.64.180502
Abstract
We have addressed the possibility of surface ferromagnetism in Sr2RuO4 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 surface reconstruction.
