Magnetic-closure domains and interpretation of spin-resolved electron spectroscopies
In spin-resolved electron spectroscopies at surfaces that do not contain an easy axis of bulk magnetisation, the detection of spin effects can be hindered by closure domains. This is demonstrated by combining the magneto-optical Kerr effect and spin-resolved inverse photoemission (IPE) using Ni(001) as an example. On a Ni(001) surface with high remanent magnetisation, spin-resolved IPE reveals a spin splitting of (80 +/- 20) meV for transitions between bulk sp bands. The discrepancy in recent spectroscopic data regarding the splitting of Ni sp bands is explained by closure domains.
