Query: Reversible vs. irreversible voltage manipulation of interfacial magnetic
  anisotropy in Pt/Co/oxide multilayers   The perpendicular magnetic anisotropy at the Co/oxide interface in Pt/Co/MOx
(MOx = MgOx, AlOx, TbOx) was modified by an electric field using a 10 nm-thick
ZrO2 as a solid electrolyte. The large voltage-driven modification of
interfacial magnetic anisotropy and the non-volatility of the effect is
explained in terms of the migration of oxygen ions towards/away from the Co/MOx
interface. While the effect is reversible in Pt/Co/AlOx and Pt/Co/TbOx, where
the Co layer can be oxidised or reduced, in Pt/Co/MgOx the effect has been
found to be irreversible. We propose that these differences may be related to
the different nature of the ionic conduction within the MOx layers.
