Abstract
The spin-resolved electronic structure at the (110) surface of the magnetic alloy FeNi3 has been studied with spin-polarized inverse photoemission spe ctroscopy in conjunction with first-principles electronic structure calcula tions. An unoccupied (Y) over bar Schockley surface state in a bulk band ga p is observed that is exchange split by 320 meV, indicating that the topmos t surface layer is ferromagnetically ordered.
