Lack of evidence for ferromagnetism in the vanadium monolayer on Ag(001)

Abstract

Spin-polarized photoemission has been used as a probe of the ferromagnetism of thin films of V on Ag(001) consisting of 1-3 monolayers. The measured electron-spin polarization at 30 K and applied magnetic fields up to 18 kOe is less than 2% for all film thicknesses. No evidence for ferromagnetism of V on Ag(001) is found. Available model calculations claiming ferromagnetism of V on Ag(001) are in disagreement with the experiment.
