Spin-polarized scanning electron microscopy [PDF]

Microscopy, 2005
Spin-polarized scanning electron microscopy (spin-SEM) is a magnetic domain observation method. In spin-SEM, polarization of secondary electrons emitted from a sample in a scanning electron microscope is detected by a spin detector and used as a signal for forming an image. The characteristics of spin-SEM are detection of all three magnetization vector

Fully spin-polarized bulk states in ferroelectric GeTe

Physical Review Research, 2020
By measuring the spin polarization of GeTe films as a function of light polarization we observed that the bulk states are fully spin polarized in the initial state, in strong contrast with observations for other systems with a strong spin-orbit ...

Spin Injection and Relaxation in Ferromagnet-Semiconductor Heterostructures

, 2004
We present a complete description of spin injection and detection in Fe/Al_xGa_{1-x}As/GaAs heterostructures for temperatures from 2 to 295 K. Measurements of the steady-state spin polarization in the semiconductor indicate three temperature regimes for ...

Spin polarization control through resonant states in an Fe/GaAs Schottky barrier [PDF]

, 2008
Spin polarization of the tunnel conductivity has been studied for Fe/GaAs junctions with Schottky barriers. It is shown that band matching of resonant interface states within the Schottky barrier defines the sign of spin polarization of electrons ...

Spin-Selective Transport of Electron in DNA Double Helix

, 2012
The experiment that the high spin selectivity and the length-dependent spin polarization are observed in double-stranded DNA [Science ${\bf 331}$, 894 (2011)], is elucidated by considering the combination of the spin-orbit coupling, the environment ...

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

Advanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Impact of strong magnetic field, baryon chemical potential, and medium anisotropy on polarization and spin alignment of hadrons

European Physical Journal C: Particles and Fields
The recent observation of global spin polarization of $$\Lambda $$ Λ ( $$\bar{\Lambda }$$ Λ ¯ ) hyperons and the spin alignment of $$\phi $$ ϕ and $$K^{*0}$$ K ∗ 0 vector mesons create remarkable interest in investigating the particle polarization in the

Hidden spin-orbital texture at the $$\overline{{{\Gamma }}}$$ Γ ¯ -located valence band maximum of a transition metal dichalcogenide semiconductor

Nature Communications, 2022
Materials with time reversal and inversion symmetry have a bulk band structure that is spin degenerate, however, they can still exhibit a hidden spin-polarization when probed in a specific way.

Spin Decoherence from Hamiltonian dynamics in Quantum Dots

, 2006
The dynamics of a spin-1/2 particle coupled to a nuclear spin bath through an isotropic Heisenberg interaction is studied, as a model for the spin decoherence in quantum dots.
