Synchrotron Radiation as CMB Foreground [PDF]

arXiv, 1999
Synchrotron emission is an important process in Galactic dynamics and a potentially confusing foreground for cosmic microwave background (CMB) radiation observations. Though the mechanism of synchrotron emission is well understood, the details for the Galaxy and many external sources are not well characterized.

Controlled Formation of Skyrmion Bags

Advanced Materials, EarlyView.
This work demonstrates stabilization of complex magnetic skyrmion bags in ferromagnetic thin films through precisely engineered anisotropy defects using ion irradiation. The researchers achieve controlled field‐ and laser‐induced generation of skyrmionia, target skyrmions, and higher‐order skyrmion bags at room temperature. This reliable platform opens

Self-cleaning and surface chemical reactions during hafnium dioxide atomic layer deposition on indium arsenide

Nature Communications, 2018
Atomic layer deposition of high-quality thin oxide layers is crucial for many modern semiconductor electronic devices. Here, the authors explore the surface chemistry during the initial deposition and observe a previously unknown two-step process, with ...

Tailoring of Creep Regime Domain Wall Dynamics in Perpendicularly Magnetized Pd/Co/Pd Trilayers

Advanced Materials Interfaces, EarlyView.
Understanding magnetic domain wall (DW) dynamics is vital for improving the performance of heavy‐metal/ferromagnet‐based spintronic devices. This work manifests a fundamental investigation encompassing structural properties and magnetic DW motion in Pd/Co/Pd multilayers having perpendicular magnetic anisotropy.

Estimation of synchrotron-radiation background based on a real beam orbit

Physical Review Special Topics. Accelerators and Beams, 2004
Some high-energy experiments have suffered from bitter experience on synchrotron-radiation background. As a measure, we have developed a new calculation method of synchrotron radiation based on a real beam orbit, aiming at quantitative estimations of ...

2D/3D Heterostructure Halide Perovskite Thin Films through an Innovative Spray‐Deposition of Bulky Organic Cation‐Containing Ammonium Salts

Advanced Materials Interfaces, EarlyView.
Spray‐depositon of bulky organic cations salts on top of 3D perovskite layers lead to formation of 2D/3D perovskite heterostructurs with 2D perovskite compositions (PEA)2FAPb2I7, (TMA)2PbI4, (CMA)2FAPb2I7, and (DDA)2FAPb2I7, respectively. Extensive characterization, including X‐ray diffraction and grazing incidence wide‐angle X‐ray scattering, confirms

Superstoichiometric reversible and manipulable copper-ion intercalation in niobium selenide

Nature Communications
Few-layer stacked niobium selenide (NbSe2) has evoked great interest owing to its intrinsically exotic properties and accessible manipulation by controlled ion intercalation for superconductivity physics and advanced device applications.

Anisotropy in the thermal hysteresis of resistivity and charge density wave nature of single crystal SrFeO3-δ: X-ray absorption and photoemission studies

Scientific Reports, 2017
The local electronic and atomic structures of the high-quality single crystal of SrFeO3-δ (δ~0.19) were studied using temperature-dependent x-ray absorption and valence-band photoemission spectroscopy (VB-PES) to investigate the origin of anisotropic ...
