Geosciences, 2020 In this study, we present a novel approach combining the advantages of tesseroids in representing geophysical structures though their voxel-like discretization features with a spherical harmonic representation of the magnetic field.

How efficient is an integrative approach in archaeological geophysics? Comparative case studies from Neolithic settlements in Thessaly (Central Greece) [PDF]
, 2015 The geophysical prospection of Neolithic tells imposes specific challenges due to the preservation and nature of the architectural context and the multiple, usually disturbed, soil strata.

XPS and XMCD study of Fe3O4/GaAs interface [PDF]
, 2005 Ultrathin Fe oxide films of various thicknesses prepared by post-growth oxidation on GaAs(100) surface have been investigated with X-ray photoelectron spectroscopy (NPS), X-ray absorption spectroscopy (XAS), and X-ray magnetic circular dichroism (XMCD ...

Earth, Planets and Space, 2020 From the launch of the Ørsted satellite in 1999, through the CHAMP mission from 2000 to 2010, and now with the Swarm constellation mission starting in 2013, satellite magnetometry has provided excellent monitoring of the near-Earth magnetic field regime.

A spatially continuous magnetization model for Mars [PDF]
, 2005 [1] Using a three-component magnetic field data set at over 100,000 satellite points previously compiled for spherical harmonic analysis, we have produced a continuously varying magnetization model for Mars.

Magnetic attitude control for satellites [PDF]
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004 In this paper it is proven that three-axis stabilization of satellites using magnetorqers is uniformly globally asymptotically stable (UGAS). The application of Matrosovs theorem allows for removal of the assumption that the geomagnetic (internal and external) field is periodic in order to establish this stability result.

Precursory worldwide signatures of earthquake occurrences on Swarm satellite data
Scientific Reports, 2019 The study of the preparation phase of large earthquakes is essential to understand the physical processes involved, and potentially useful also to develop a future reliable short-term warning system.

On spinodal decomposition in alnico---a transmission electron microscopy and atom probe tomography study [PDF]
, 2018 Alnico is a prime example of a finely tuned nanostructure whose magnetic properties are intimately connected to magnetic annealing (MA) during spinodal transformation and subsequent lower temperature annealing (draw) cycles.
