High‐Temperature Magnetic Field Mapping Using a Single‐Crystal Diamond MEMS Resonator Array

Advanced Science, EarlyView.
A single‐crystal diamond MEMS resonator array enables magnetic‐field reconstruction with millisecond response, nanotesla level magnetic noise, and stable operation up to 573 K. Two‐ and three‐dimensional magnetic field mapping are demonstrated using ΔEeffect sensing, highlighting the potential of diamond MEMS technology for hightemperature magnetic ...

Cr1/4NbSe2‐Single Crystal Growth and Evolution of Antiferromagnetic Correlated States

Advanced Science, EarlyView.
High‐quality single crystals Cr1/4NbSe2 were synthesized and comprehensively characterized for the first time. Advanced structural, electronic, and magnetic measurements uncover a correlated antiferromagnetic state, resolving longstanding inconsistencies regarding magnetic behavior derived from earlier polycrystal studies.

Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

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,

Salience network hub dysfunction is associated with cognitive impairment in self‐limited epilepsy with centrotemporal spikes: An OPM‐MEG study

Epilepsia Open, EarlyView.
Abstract Objective Self‐limited epilepsy with centrotemporal spikes (SeLECTS), although characterized by well‐controlled seizures, is frequently associated with persistent cognitive deficits in affected children. This study aimed to investigate whether hub dysfunction of the salience network (SN) is associated with cognitive impairment in SeLECTS ...

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.

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3

Small, EarlyView.
Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...
