Coexistence and coupling of ferroelectricity and ferromagnetism in an oxide two-dimensional electron gas

<p>The dataset contains X-ray absorption spectroscopy (XAS), electric polarization and magnetotransport measurements obtained on LaAlO3/EuTiO3/Ca:SrTiO3 heterostructures, at which interface a two-dimensional electron gas appears.</p> <p>X-ray magnetic circular dichroism (XMCD) extracted from the XAS data are also included, as well as X-ray linear dichroism (XLD) alongside atomic multiplet calculations for two sets of parameters corresponding to &quot;up&quot; and &quot;down&quot; remanent polarization states (data of Fig. 1 and 2).</p>
