Magnetic skyrmion field-effect transistors [PDF]

Applied Physics Letters, 2019
Magnetic skyrmions are of considerable interest for low-power memory and logic devices because of high speed at low current and high stability due to topological protection. We propose a skyrmion field-effect transistor based on a gate-controlled Dzyaloshinskii-Moriya interaction. A key working principle of the proposed skyrmion field-effect transistor

Effective Magnetic Fields for Stationary Light [PDF]

Physical Review Letters, 2010
We describe a method to create effective gauge potentials for stationary-light polaritons in two or three spatial dimensions. When stationary light is created in the interaction with a uniformly rotating ensemble of coherently driven double $ $ atoms, the equation of motion is that of a massive Schr dinger particle in an effective magnetic field.

Chiral effects and cosmic magnetic fields [PDF]

Physical Review D, 2012
In the presence of cosmic chiral asymmetry, chiral-vorticity and chiral-magnetic effects can play an important role in the generation and evolution of magnetic fields in the early universe. We include these chiral effects in the magnetic field equations and find solutions under simplifying assumptions.

Revisiting Nucleosynthesis Constraints on Primordial Magnetic Fields [PDF]

, 1996
In view of several conflicting results, we reanalyze the effects of magnetic fields on the primordial nucleosynthesis. In the case the magnetic field is homogeneous over a horizon volume, we show that the main effects of the magnetic field are given by ...

Mitigation of magnetic particle hyperthermia side effects by magnetic field controls

International Journal of Hyperthermia, 2021
Objective: In magnetic particle hyperthermia, a promising least-invasive cancer treatment, malignant regions in proximity with magnetic nanoparticles undergo heat stress, while unavoidably surrounding healthy tissues may also suffer from heat either ...

Population Synthesis of Pulsars: Magnetic Field Effects [PDF]

, 2001
New results based on methods of population synthesis, concerning magnetic field effects on the evolution of pulsars are reported. The present study confirms that models with timescales for the magnetic field decay longer than the pulsar lifetime are in ...

Influence of Magnetic Field on Evaporation Rate and Surface Tension of Water

Colloids and Interfaces, 2018
Using neodymium ring magnets (0.5⁻0.65 T), the experiments on the magnetic field (MF) effects on water evaporation rate and surface tension were performed at room temperature (22⁻24 °C).

Electrical Treeing of SiR and SiR/Fe₃O₄ Nanocomposites in High Magnetic Field

IEEE Access, 2023
This paper investigates the effects of high magnetic field on electrical treeing of silicone rubber (SiR). Experimental results show that electrical trees are more easily to be initiated and spread further along the direction of electric field under the ...

Enhanced modulation bandwidth of GaAlAs double heterostructure lasers in high magnetic fields: Dynamic response with quantum wire effects [PDF]

, 1985
The modulation bandwidth of GaAlAs double heterostructure (DH) lasers in high magnetic fields is measured. We found that the modulation bandwidth is enhanced by 1.4× with a magnetic field of 20 T.

Effective Magnetic Fields in Graphene Superlattices [PDF]

Physical Review Letters, 2010
We demonstrate that the electronic spectrum of graphene in a one-dimensional periodic potential will develop a Landau level spectrum when the potential magnitude varies slowly in space. The effect is related to extra Dirac points generated by the potential whose positions are sensitive to its magnitude.
