Abstract

Co/BaTiO3_3(001) is one of the most interesting multiferroic heterostructures as it combines different ferroic phases, setting this way the fundamentals for innovative technical applications. Various theoretical approaches have been applied to investigate the electronic and magnetic properties of Co/BaTiO3_3(001). Here we determine the magnetic properties of 3 ML Co/BaTiO3_3 by calculating spin-polarized electron diffraction as well as angle-resolved photoemission spectra, with both methods being well established as surface sensitive techniques. Furthermore, we discuss the impact of altering the BaTiO3_3 polarization on the spectra and ascribe the observed changes to characteristic details of the electronic structure.
