GEOMAGNETIC FIELD OF UKRAINE: ESTIMATION OF INTERNAL AND EXTERNAL SOURCES CONTRIBUTION

Odessa Astronomical Publications, 2012
This article is considering some aspects of differentiation between internal and external sources of the Earth's magnetic field; it estimates also the contribution of different sources into total field as well as its variations.

Exchange bias and its phase reversal in the zero magnetization admixed rare earth intermetallics [PDF]

IEEE Transactions on Magnetics 45, 2902 (2009), 2008
Exchange bias effect is an important attribute in several device applications. Traditionally, it is discussed as a form of exchange anisotropy at the interface between the ferromagnetic/antiferromagnetic layers of two distinct systems. We report here on the magnetically ordered alloys possessing the feature of unidirectional anisotropy, which reverses ...

Quantum Emitters in Hexagonal Boron Nitride: Principles, Engineering and Applications

Advanced Functional Materials, EarlyView.
Quantum emitters in hexagonal boron nitride have emerged as a promising candidate for quantum information science. This review examines the fundamentals of these quantum emitters, including their level structures, defect engineering, and their possible chemical structures.

Measuring Earth's Magnetic Field Using a Smartphone Magnetometer [PDF]

arXiv, 2018
I use the magnetometers of a smartphone to measure the magnitude of the earth's magnetic field. A method for eliminating bias due to internal magnetic fields in the phone is proposed.

Iridium Communications Satellite Constellation Data for Study of Earth's Magnetic Field

Geochemistry, Geophysics, Geosystems, 2021
Characterization of Earth's magnetic field is key to understanding dynamics of the core. We assess whether Iridium Communications magnetometer data can be used for this purpose since.

Trajectories of charged particles trapped in Earth's magnetic field

, 2011
I outline the theory of relativistic charged-particle motion in the magnetosphere in a way suitable for undergraduate courses. I discuss particle and guiding center motion, derive the three adiabatic invariants associated with them, and present particle ...

High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite

Advanced Functional Materials, EarlyView.
This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.

Modeling the Young Sun's Solar Wind and its Interaction with Earth's Paleomagnetosphere [PDF]

, 2011
We present a focused parameter study of solar wind - magnetosphere interaction for the young Sun and Earth, $~3.5$ Ga ago, that relies on magnetohydrodynamic (MHD) simulations for both the solar wind and the magnetosphere.
