Magnetic Proximity Effects between Single-Layer Mn-Doped Titania Nanosheets and Fe Overlayers
2016
We have investigated the magnetic behaviors of molecularly thin Mn-doped titanium oxide nanosheets by X-ray magnetic circular dichroism. Mn atoms in single-layer nanosheets showed a weak ferromagnetic order at room temperature. Fe overlayers deposited on the nanosheets induced a magnetic proximity effect on Mn magnetization. We clearly observed an antiferromagnetic coupling between the Fe overlayers and the Mn-doped nanosheets.
