Minority-spin states for v and Mn on Ag(111) by inverse photoemission

View publication

Abstract

Unoccupied states have been observed with momentum-resolved inverse photoemission for thin layers of V and Mn on Ag(111) ranging from 0.2 monolayer to thick bulklike films. An assignment in terms of exchange- and crystal-field-split 3d states is given by comparison with similar data from the Mn-in-Ag spin glass and with first-principles calculations. The states are located at 0.9 and 1.8 eV above EF for Mn and at 0.5 and 1.7 eV above EF for V. The data are consistent with large magnetic moments for V and Mn films up to a monolayer, in contrast to the absence of ferromagnetism in the bulk materials. © 1987 The American Physical Society.
