Indium Tin Oxide optical access for magnetic tunnel junctions in hybrid spintronic-photonic circuits
(IOP Publishing, 2020-10)
The all-optical magnetization reversal of magnetic layers, by picosecond optical pulses, is of particular interest as it shows the potential for energy-efficient and fast magnetic tunnel junction (MTJ) elements. This ...
Signatures of tunneling and multiphoton ionization in the electron-momentum distributions of atoms by intense few-cycle laser pulses
(American Physical Society, 2006-12)
Electron-momentum distributions for above-threshold ionization of argon in a few-cycle, linearly polarized laser pulse are investigated. Spectral features haracteristic of multiphoton as well as tunneling ionization coexist ...
Efficient Spin-Flip Excitation of a Nickelocene Molecule
(American Chemical Society, 2017-03)
Inelastic electron tunneling spectroscopy (IETS) within the junction of a scanning tunneling microscope (STM) uses current-driven spin-flip excitations for an all-electrical characterization of the spin state of a single ...
Formation of graphitic films on Cu(111) via electron beam induced deposition
(Pergamon-Elsevier Science Ltd, 2020-10)
Electron beam induced deposition using ethylene as precursor gas is used to generate carbonaceous films on Cu(111). The study was performed in an ultrahigh vacuum chamber for two different precursor gas pressures, and two ...
Characterization of Tunneling Nanotubes in Wharton’s jelly Mesenchymal Stem Cells. An Intercellular Exchange of Components between Neighboring Cells
(Springer Heidelberg, 2017-08)
Intercellular communication is one of the most important events in cell population behavior. In the last decade, tunneling nanotubes (TNTs) have been recognized as a new form of long distance intercellular connection. TNT ...
Vázquez de Parga et al. Reply
(American Physical Society, 2008-12)
The Comment by B. Wang et al. [1] states that according to their ab initio calculation, the periodically rippled graphene monolayer epitaxially grown on Ru(0001), whose spatially resolved electronic structure we unravelled ...
Spin excitations of weakly coupled magnetic atoms
(American Physical Society, 2015-04)
Atheoretical description of the measured differential conductance through magnetic atoms on a Cu2N/Cu(100) substrate is presented [Otte et al., Phys. Rev. Lett. 103, 107203 (2009)]. In particular, we analyze the case of ...
Theory of Differential Conductance of Co on Cu(111) including Co s and d Orbitals, and Surface and Bulk Cu States
(American Physical Society, 2021-01)
We revisit the theory of the Kondo effect observed by a scanning-tunneling microscope (STM) for transition-metal atoms (TMAs) on noble-metal surfaces, including d and s orbitals of the TMA, surface and bulk conduction ...
From tunneling to contact in a magnetic atom: The non-equilibrium Kondo effect
(American Institute of Physics, 2017-03)
A low-temperature scanning tunneling microscope was employed to study the differential conductance in an atomic junction formed by an adsorbed Co atom on a Cu(100) surface and a copper-covered tip. A zero-bias anomaly (ZBA) ...
Tuning the Exchange Bias on a Single Atom from 1 mT to 10 T
(American Physical Society, 2019-06)
Shrinking spintronic devices to the nanoscale ultimately requires localized control of individual atomic magnetic moments. At these length scales, the exchange interaction plays important roles, such as in the stabilization ...
