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.

Field-induced quantum spin disordered state in spin-1/2 honeycomb magnet Na2Co2TeO6 [PDF]

Nature Communications, 2020
Spin-orbit coupled honeycomb magnets with the Kitaev interaction have received a lot of attention due to their potential of hosting exotic quantum states including quantum spin liquids.

Complexity of magnetization and magnetic simplification

Physical Review D, 2023
We use the complexity=volume (CV) prescription to study the effect of a magnetic field on the computational complexity for states in the gauge theories dual to two different gravitational models. In one of these theories the complexity increases with the intensity of the magnetic field, while in the other a more interesting behavior is discovered ...

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

Impulse Magnetized Magnetic Screws [PDF]

IEEE Transactions on Magnetics, 2019
This paper is an investigation in the performance of two types of magnetic screws (MSs). The first is the magnet to magnet and consists of permanent magnet (PM) nut and PM screw and the second is a magnet to reluctance and consists of PM nut and a double-start reluctance screw.

Effects of shrink fitting on iron losses of a permanent magnet synchronous motor with an amorphous core

IET Electric Power Applications, 2022
In order to investigate the effects of shrink fitting on the amorphous core, a test device is designed and the magnetisation and specific iron loss characteristics of the amorphous core are measured.
