Description
In this paper we investigate the surface spin polarization in a 100 nm Co2Cr0.6Fe0.4Al film grown ex situ epitaxially on MgO(1 0 0) with a 10 nm Fe buffer layer by means of spin-resolved photoemission. We show that a careful in situ preparation of the sample surface leads to values for the room temperature spin polarization up to 45% at the Fermi level. To our knowledge, this is the highest value measured so far at the surface region of a full Heusler alloy at room temperature
