Second generation of CSES global geomagnetic field model (CGGM-2) and associated candidate models for IGRF-14

Earth, Planets and Space
This paper presents the second generation of the China Seismo-Electromagnetic Satellite (CSES) Global Geomagnetic Field Model (CGGM-2), specifically designed to derive candidate models for the fourteenth generation of the International Geomagnetic ...

Domain-resolved room-temperature magneto-electric coupling in manganite-titanate heterostructures [PDF]

, 2015
We present a model artificial multiferroic system consisting of a (011)-oriented ferroelectric Pb(Mg,Nb,Ti)O$_3$ substrate intimately coupled to a ferromagnetic (La,Sr)MnO$_3$ film through epitaxial strain and converse piezoelectric effects.

Nanotesla torque magnetometry using a microcantilever [PDF]

, 2008
We present a novel ultrasensitive magnetometry technique using a micromachined magnetic antilever that is brought in resonance. The induced magnetic moment generates a torque on the cantilever, thereby effectively stiffening the cantilever spring ...

Swarm optimization for adaptive phase measurements with low visibility

, 2013
Adaptive feedback normally provides the greatest accuracy for optical phase measurements. New advances in nitrogen vacancy centre technology have enabled magnetometry via individual spin measurements, which are similar to optical phase measurements but ...

Magnetic Diagnostics of Prominence Eruptions through the Hanle Effect of the He i 1083 nm Line

The Astrophysical Journal
The magnetic field vector of the solar corona is not regularly and comprehensively being measured because of the complexity and degeneracy inherently present in the types of observations currently available.

Identification of animal movement patterns using tri-axial magnetometry

Movement Ecology, 2017
Background Accelerometers are powerful sensors in many bio-logging devices, and are increasingly allowing researchers to investigate the performance, behaviour, energy expenditure and even state, of free-living animals.

High‐Resolution Magnetic‐Geochemical Mapping of the Serpentinized and Carbonated Atlin Ophiolite, British Columbia: Toward Establishing Magnetometry as a Monitoring Tool for In Situ Mineral Carbonation

Geochemistry, Geophysics, Geosystems, 2023
We address in situ serpentinization and mineral carbonation processes in oceanic lithosphere using integrated field magnetic measurements, rock magnetic analyses, superconducting quantum interference device (SQUID) microscopy, microtextural observations,

Topological Hall effect in thin films of Mn$_{1.5}$PtSn

, 2018
Spin chirality in metallic materials with non-coplanar magnetic order can give rise to a Berry phase induced topological Hall effect. Here, we report the observation of a large topological Hall effect in high-quality films of Mn$_{1.5}$PtSn that were ...

Quantitative nanoscale vortex-imaging using a cryogenic quantum magnetometer [PDF]

, 2015
Microscopic studies of superconductors and their vortices play a pivotal role in our understanding of the mechanisms underlying superconductivity. Local measurements of penetration depths or magnetic stray-fields enable access to fundamental aspects of ...
