Anisotropy of magnetic damping in Ta/CoFeB/MgO heterostructures

Scientific Reports, 2023
Magnetic damping controls the performance and operational speed of many spintronics devices. Being a tensor quantity, the damping in magnetic thin films often shows anisotropic behavior with the magnetization orientation.

Spin-excitation anisotropy in the bilayer iron-based superconductor CaKFe_{4}As_{4}

Physical Review Research, 2020
We use polarized inelastic neutron scattering to study the spin-excitation anisotropy in the bilayer iron-based superconductor CaKFe_{4}As_{4} (T_{c}=35 K).

Magnetic Guinier law

IUCrJ, 2020
Small-angle scattering of X-rays and neutrons is a routine method for the determination of nanoparticle sizes. The so-called Guinier law represents the low-q approximation for the small-angle scattering curve from an assembly of particles.

Superfluid Phase Stability of $^3$He in Axially Anisotropic Aerogel [PDF]

, 2008
Measurements of superfluid $^3$He in 98% aerogel demonstrate the existence of a metastable \emph{A}-like phase and a stable \emph{B}-like phase.

Scattering anisotropy in HgTe (013) quantum well

Applied Physics Letters, 2022
We report on a detailed experimental study of the electron transport anisotropy in HgTe (013) quantum well of 22 nm width in the directions [100] and [031¯] as the electron density function n. The anisotropy is absent at the minimal electron density near a charge neutrality point.

In Vitro Assessment of Optical Properties of Blood by Applying the Extended Huygens-Fresnel Principle to Time-Domain Optical Coherence Tomography Signal at 1300 nm

International Journal of Biomedical Imaging, 2008
A direct method for the measurement of the optical attenuation coefficient and the scattering anisotropy parameter based on applying the extended Huygens-Fresnel principle to optical coherence tomography images of blood is demonstrated.

High-accuracy measurements of snow Bidirectional Reflectance Distribution Function at visible and NIR wavelengths – comparison with modelling results [PDF]

Atmospheric Chemistry and Physics, 2010
High-accuracy measurements of snow Bidirectional Reflectance Distribution Function (BRDF) were performed for four natural snow samples with a spectrogonio-radiometer in the 500–2600 nm wavelength range.

On the spectrum of discrete-ordinates neutron transport problems

Brazilian Journal of Radiation Sciences, 2021
Over the last six decades, the discrete spectrum of the neutron transport operator has been widely studied. Important theoretical results can be found in the literature regarding the one-speed linear transport equation with anisotropic scattering.

Penetration depth anisotropy in two-band superconductors

, 2003
The anisotropy of the London penetration depth is evaluated for two-band superconductors with arbitrary inter- and intra-band scattering times. If one of the bands is clean and the other is dirty in the absence of inter-band scattering, the anisotropy is

Light scattering by optically anisotropic scatterers II: T--matrix computations for radially and uniformly anisotropic droplets [PDF]

, 2001
This is the second paper in a series on light scattering from optically anisotropic scatterers embedded in an isotropic medium. The apparently complex T-matrix theory involving mixing of angular momentum components turns out to be an efficient approach ...
