Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

Advanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

Four-channel optically pumped atomic magnetometer for magnetoencephalography

Optics Express, 2016
We have developed a four-channel optically pumped atomic magnetometer for magnetoencephalography (MEG) that incorporates a passive diffractive optical element (DOE). The DOE allows us to achieve a long, 18-mm gradiometer baseline in a compact footprint on the head.

Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

Advanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Comparison of sensor localization methods for Optically Pumped Magnetometers

Current Directions in Biomedical Engineering
Optically pumped magnetometers (OPMs) are magnetic field sensors which can be used for different biomedical applications. Due to their modularity and small size, they can be flexibly arranged over the region of interest.

An Optically Pumped Magnetometer with Omnidirectional Magnetic Field Sensitivity

Sensors, 2023
In mobile applications such as geomagnetic surveying, two major effects hamper the use of optically pumped magnetometers: dead zones, sensor orientations where the sensors signal amplitude drops; and heading errors, a dependence of the measured magnetic field value on the sensor orientation.

Comparison of noise levels of two magnetometer types and their suitability for different space environments [PDF]

Geoscientific Instrumentation, Methods and Data Systems
The plasma environment around Earth has markedly different characteristics of the magnetic field across distinct spatial regions. In the solar wind, beyond Earth's magnetic influence, the magnetic field is relatively low and less fluctuating. In contrast,

Study of ³He Rabi nutations by optically-pumped cesium magnetometers [PDF]

, 2017
We describe a method for recording the Rabi nutation of nuclear spin polarized ³He by optically pumped cesium magnetometers. The measurement is performed by detecting the time-dependent magnetic field produced by the 3He magnetization.

The Interplay of Magnetic Order with the Electronic Scattering and Crystal‐Field Effects in a Metallic Ferromagnet

Advanced Science, EarlyView.
The interplay between magnetic ordering and crystal electric field (CEF) excitations plays a pivotal role in defining the low‐energy electrodynamics of quantum materials. By probing the temperature‐dependent THz conductivity in a rare‐earth‐based metallic ferromagnet, we uncover a microscopic connection between localized and itinerant electrons ...
