Beam Measurements of Full Stokes Parameters for the FAST L-band 19-beam Receiver

The Astronomical Journal
The Five-hundred-meter Aperture Spherical radio Telescope (FAST) has been fully operational since 2020 January 11. We present a comprehensive analysis of the beam structure for each of the 19 feed horns on FAST's L -band receiver across the Stokes I , Q ,

Disorder Scattering Induced Large Room Temperature Nonlinear Anomalous Hall Effect in a Semiconductor CdGeAs2

Advanced Materials, EarlyView.
Bulk CdGeAs2, a well‐known nonlinear optical semiconductor, exhibits an exceptionally large room‐temperature nonlinear Hall effect (NLHE), achieving a record‐high nonlinear Hall responsivity of 2.2 × 10−3 m/V. This pronounced NLHE enables broadband frequency mixing up to the megahertz regime, establishing CdGeAs2 as a promising platform for next ...

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

Advanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Field‐Free, Deterministic Giant Spin‐Orbit Torque Switching of 1.3 T Perpendicular Magnetization With Symmetry‐Lifted Topological Surface States

Advanced Materials, EarlyView.
We show a giant, bias‐field free, deterministic, spin‐orbit‐torque switching of perpendicular hard magnets with HC over 1.3 T. By combining the three‐fold 3m symmetry from topological insulator surface states with the rectangular mm2 symmetry from the 2 x 1 intercalation in Cr3Te4, the interface symmetry is significantly reduced into a unidirectional m

Designing Defect Structure and Interfacial Strain in an Epitaxial VN Bilayer Film by Tailoring N Concentration

Advanced Materials Interfaces, EarlyView.
The N concentration in an epitaxial VN bilayer is tailored from overstoichiometric V0.49N0.51 to understoichiometric V0.56N0.44. Based on ab initio, diffraction, and microscopy data, the overstoichiometric V0.49N0.51 layer contains V vacancies, N Frenkel pairs, and a high density of dislocations.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
