The persistence of electronic states exhibiting spin-degeneracy lifting in ultrathin films is of particular importance in the context of device miniaturization.<br \/>\nUsing angle- and spin-resolved photoemission spectroscopy (SR-ARPES) supported by <i>ab initio<\/i> calculations, research teams from CINaM (AMU\/CNRS), the Institut Jean Lamour (Univ. Lorraine\/CNRS), and the SOLEIL synchrotron have demonstrated that \ud835\udefc-GeTe films as thin as 5 nm still exhibit a spin texture at the Fermi surface.
