The MAVEN Magnetic Field Investigation

open access: yes, 2015
The MAVEN magnetic field investigation is part of a comprehensive particles and fields subsystem that will measure the magnetic and electric fields and plasma environment of Mars and its interaction with the solar wind. The magnetic field instrumentation

Magnetic fluctuations and formation of large-scale inhomogeneous magnetic structures in a turbulent convection [PDF]

open access: yesPhys.Rev.E76:056307,2007, 2007
Magnetic fluctuations generated by a tangling of the mean magnetic field by velocity fluctuations are studied in a developed turbulent convection with large magnetic Reynolds numbers. We show that the energy of magnetic fluctuations depends on magnetic Reynolds number only when the mean magnetic field is smaller than $B_{eq} / 4 Rm^{1/4}$, where $B_{eq}

Magnetic helicity and cosmological magnetic field

open access: yes, 2004
The magnetic helicity has paramount significance in nonlinear saturation of galactic dynamo. We argue that the magnetic helicity conservation is violated at the lepton stage in the evolution of early Universe.

THE GALACTIC MAGNETIC FIELD [PDF]

open access: yesThe Astrophysical Journal, 2012
With this Letter, we complete our model of the Galactic magnetic field (GMF), by using the WMAP7 22 GHz total synchrotron intensity map and our earlier results to obtain a 13-parameter model of the Galactic random field, and to determine the strength of the striated random field.

Single Crystal Growth of URu2Si2 by the Modified Bridgman Technique

open access: yesCrystals, 2016
We describe a modified Bridgman growth technique to produce single crystals of the strongly correlated electron material URu2Si2 and its nonmagnetic analogue ThRu2Si2.

Cosmological magnetic field survival

open access: yes, 2011
It is widely believed that primordial magnetic fields are dramatically diluted by the expansion of the universe. As a result, cosmological magnetic fields with residual strengths of astrophysical relevance are generally sought by going outside standard ...

The apo LETM1 F‐EF‐hand adopts a closed conformation that underlies a multi‐modal sensory role in mitochondria

open access: yesFEBS Letters, EarlyView.
We present the first solution structure of the Ca2+‐depleted LETM1 F‐EF‐hand through a D676A/N678A Ca2+ binding‐deficient mutant, revealing a closed hydrophobic cleft caused by a unique F1‐helix pivot. The apo LETM1 F‐EF‐hand exhibits regiospecific hot and cold unfolding, sensitivity to physiological pH changes and potential for promiscuous heterotypic

Perspective: Magnetic skyrmions—Overview of recent progress in an active research field

open access: yesJournal of Applied Physics, 2018
Within a decade, the field of magnetic skyrmionics has developed from a niche prediction to a huge and active research field. Not only do magnetic skyrmions—magnetic whirls with a unique topology—reveal fundamentally new physics, but they have also risen

Evidence that transverse variability of critical current density can greatly mitigate screening current stress in high field REBCO magnets

open access: yesScientific Reports
Plastic damage of REBCO (REBa2Cu3O7-x, where RE=rare earth) coated conductors by screening current stress (SCS) is a significant concern for ultra-high-field superconducting magnets. Indeed, the third Little Big Coil (LBC3), a REBCO magnet that generated

Transforming magnets [PDF]

open access: yes, 2014
Based on the form-invariant of Maxwell's equations under coordinate transformations, we extend the theory of transformation optics to transformation magneto-statics, which can design magnets through coordinate transformations. Some novel DC magnetic field illusions created by magnets (e.g.
