X-ray-absorption dichroism of Dy at interfaces.
نویسنده
چکیده
The linearly polarized x-ray-absorption dichroism at the Dy 3d-4f edge is studied for three dilerent kinds of interfaces: Dy on disordered Si(111),Dy on amorphous Si02, and Dy on polycrystalline Ta. Strong dichroism is observed in all the three interfaces, despite the very different interactions of Dy with the substrates. It is therefore pointed out that the x-ray-absorption dichroism using linearly polarized light is a more widespread, but at the same time complicated, phenomenon than previously suspected.

We have analyzed the interface structure and composition of La0.7Ca0.3MnO3/YBa2Cu3O7/La0.7Ca0.3MnO3 trilayers by combined polarized neutron reflectometry, aberration-corrected microscopy, and atomic column resolution electron-energy-loss spectroscopy and x-ray absorption with polarization analysis. We find the same stacking sequence at both top and bottom cuprate interfaces. X-ray magnetic circ...

A number of recent transport and magnetization studies have shown signs of ferromagnetism in the LaAlO3/SrTiO3 heterostructure, an unexpected property with no bulk analogue in the constituent materials. However, no experiment thus far has provided direct information on the host of the magnetism. Here we report spectroscopic investigations of the magnetism using element-specific techniques, incl...
متن کاملCharacterization for strontium titinateÕFe3O4 and TiNÕFe3O4 interfaces
The interface formation between different thicknesses of strontium titanate (SrTiO3) or titanium nitride ~TiN! with a 2000 Å Fe3O4 film is studied using x-ray absorption spectroscopy ~XAS! and x-ray magnetic circular dichroism ~XMCD!. Our results show that the deposition of 10–50 Å of TiN results in an immediate and substantial removal of oxygen from the near interface region, resulting in the ...
متن کاملSurface aligned magnetic moments and hysteresis of an endohedral single-molecule magnet on a metal.
The interaction between the endohedral unit in the single-molecule magnet Dy_{2}ScN@C_{80} and a rhodium (111) substrate leads to alignment of the Dy 4f orbitals. The resulting orientation of the Dy_{2}ScN plane parallel to the surface is inferred from comparison of the angular anisotropy of x-ray absorption spectra and multiplet calculations in the corresponding ligand field. The x-ray magneti...

We used x-ray absorption spectroscopy and x-ray magnetic circular dichroism to investigate the effects of inserting Cu into Co/Pt interfaces, and found that a 0.4-nm-thick inserted Cu layer showed perpendicularly magnetized properties induced by the proximity effect through the Co and Pt layers. The dependence of the magnetic properties on the thickness of the Cu layers showed that the proximit...
