Description
We study ultra-thin films of Fe magneto-electrically coupled with a ferroelectric substrate PMN-PT (001) .We have grown ultra-thin wedge of Fe with thickness varying from 1 ML to 5 ML on PMN-PT (001) under ultra-high vacuum conditions. We employed x-ray magnetic circular di-chroism (XMCD) technique at, the Fe L3, 2-edges. The results for the Fe wedge (1-5 ML) shows that the thinner part (1 ML) is paramagnetic while the thicker part (5 ML) is ferromagnetic. Furthermore, we measured a change in the remanent spin magnetic moment for 5 ML of Fe upon switching the ferroelectric polarization of PMN-PT (001).
