Direct observation of ferromagnetic spin polarization in gold nanoparticles.
We report the first direct observation of ferromagnetic spin polarization of Au nanoparticles with a mean diameter of 1.9 nm using x-ray magnetic circular dichroism (XMCD). Owing to the element selectivity of XMCD, only the gold magnetization is explored. Magnetization of gold atoms as estimated by XMCD shows a good agreement with results obtained by conventional magnetometry. This evidences in...
متن کاملLarge Superconducting Spin Valve Effect and Ultrasmall Exchange Splitting in Epitaxial Rare-Earth-Niobium Trilayers.
Epitaxial Ho/Nb/Ho and Dy/Nb/Dy superconducting spin valves show a reversible change in the zero-field critical temperature (ΔT(c0)) of ∼400 mK and an infinite magnetoresistance on changing the relative magnetization of the Ho or Dy layers. Unlike transition-metal superconducting spin valves, which show much smaller ΔT(c0) values, our results can be quantitatively modeled. However, the fits re...
متن کاملObservation of standard spin-switch effects in ferromagnet/superconductor/ferromagnet trilayers with a strong ferromagnet
We have measured the superconducting transition temperature Tc of ferromagnet/superconductor/ ferromagnet trilayers using Permalloy Py=Ni84Fe16 as a strongly polarized ferromagnetic material. For a parallel P or antiparallel AP alignment of the magnetization directions of the outer ferromagnets, we observe a Tc difference as large as 20 mK, with a stronger suppression of superconductivity in th...
متن کاملDirect correlation of Cr 3d orbital polarization and O K-edge X-ray magnetic circular dichroism of epitaxial CrO2 films
– The role of delocalization and hybridization in complex magnetic oxides has been investigated by magnetic oxygen K-edge absorption of circular polarized soft X-rays in epitaxial grown CrO2 as a function of the azimuthal angle at grazing incidence. Unusual strong variations in the typically small X-ray magnetic circular dichroism (XMCD) signal have been observed. Those angular dependencies of ...
متن کاملObservation of resistively detected hole spin resonance and zero-field pseudo-spin splitting in epitaxial graphene
Electronic carriers in graphene show a high carrier mobility at room temperature. Thus, this system is widely viewed as a potential future charge-based high-speed electronic material to complement-or replace-silicon. At the same time, the spin properties of graphene have suggested improved capability for spin-based electronics or spintronics and spin-based quantum computing. As a result, the de...
