Nanometric square skyrmion lattice in a centrosymmetric tetragonal magnet [PDF]

Nature Nanotechnology, 2020
Magnetic skyrmions are topologically stable spin swirls with a particle-like character and are potentially suitable for the design of high-density information bits.

Skyrmion Lattice in a Chiral Magnet [PDF]

Science, 2009
Skyrmions represent topologically stable field configurations with particle-like properties. We used neutron scattering to observe the spontaneous formation of a two-dimensional lattice of skyrmion lines, a type of magnetic vortex, in the chiral ...

Research on distribution of winding leakage magnetic field of three-phase dry type transformer under short-circuit condition

Energy Reports, 2023
Leakage flux magnitude and pattern greatly affect transformer short-circuit resistance. In this paper, finite element calculations and experimental measurements is used to calculate the leakage magnetic field of a transformer.

Host age structure reshapes parasite symbiosis: collaboration begets pathogens, competition begets virulent mutualists

Biology Direct, 2022
Background Symbiotic relationships are ubiquitous in the biosphere. Inter-species symbiosis is impacted by intra-specific distinctions, in particular, those defined by the age structure of a population.

Analysis of temperature characteristics of power transformer withstand short circuit shock for two seconds

Energy Reports, 2023
The occurrence of a short-circuit fault in a transformer results in a rapid increase in the short-circuit current, and the temperature of the transformer winding rises rapidly.

Skyrmion lattice with a giant topological Hall effect in a frustrated triangular-lattice magnet [PDF]

Science, 2018
Skyrmions in a frustrated magnet Skyrmions—tiny, topologically protected whirlpools of spin—have been investigated as potential information carriers in spintronic devices. Usually, skyrmions appear in noncentrosymmetric materials or at interfaces between

Development of a rapid cooling atomizing method and production of high-Bs nanocrystalline powders containing large-sized particles

AIP Advances, 2020
We attempted to produce nanocrystalline soft magnetic powders with a high saturation magnetic flux density (Bs) and containing large-sized particles using a modified water atomization system named “HPWA/YK.” Almost fully amorphous powders containing ...
