Fundamental magnetic properties of Greigite (Fe3S4) [PDF]

open access: yes, 2009
Over the last twenty years, greigite (Fe3S4), an authigenic magnetic iron sulphide mineral, has been increasingly identified in sulphate-reducing marine and lacustrine sedimentary systems.

Physics-guided attention-aware convolutional neural networks for identification of magnetic islands in the tearing mode on EAST tokamak

open access: yesNuclear Fusion
The tearing mode (TM), a large-scale magnetohydrodynamic instability in tokamak, typically disrupts the equilibrium magnetic surfaces, leads to the formation of magnetic islands, reduces core electron temperature and density, thus resulting in ...

On the magnetic anomaly at Easter Island during the 2010 Chile tsunami

open access: yesTheoretical and Applied Mechanics Letters, 2015
A magnetic anomaly was recorded at Easter Island on 27 February 2010 during the Chile tsunami event. The physics of the magnetic anomaly is analyzed using kinematic dynamo theory.

Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids

open access: yesAdvanced Materials, EarlyView.
Strong dipole–dipole interactions give rise to an emergent polar smectic phase with spontaneous chiral symmetry breaking. This resulting polar heliconical smectic superstructure enables novel functionalities in polar fluids, such as color modulation driven by electric field strength and frequency, as well as second‐harmonic generation amplification ...

Magnetic island formation in tokamaks [PDF]

open access: yes, 1989
The size of a magnetic island created by a perturbing helical field in a tokamak is estimated. A helical equilibrium of a current- carrying plasma is found in a helical coordinate and the helically flowing current in the cylinder that borders the plasma ...

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

open access: yesAdvanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Cold Pulse Propagation Inside the Magnetic Island [PDF]

open access: yes, 2010
The sign of the curvature of the space potential depends on the radial electric field at the boundary of the magnetic island. The heat transport inside the magnetic island is studied with a cold pulse propagation technique.

The relation between magnetic hysteresis and the micromagnetic state explored by quantitative magnetic force microscopy [PDF]

open access: yes, 2006
Since the discovery of magnetic lodestones in 600 BC described by ancient Greek philosophers, the mystery of magnetism has continued to intrigue. For thousands of years, these lodestones were more of a curiousity until medieval explorers discovered ...
