CONSTITUTION:In the fundamental equation in a static magnetic field, H is the intensity of magnetic field, B is magnetic flux density, M is magnetization, J0 is exciting current density and mu0 is magnetic permeability of vacuum. When magnetic vector potential A is defined by B=rot A, a ...
We study the effect of finite electric field on the density of states (DOS) in a two-dimensional disordered system, extending our previous work about the magnetic field effect. Two cases are considered: (i) uniform electric field E and (ii) crossing fields E and H. The electric field supp...
The second: the solar magnetic field (MFs) from synoptic magnetographs. The third: CI measured at the east limb. And the fourth (bottom) panel: CI at the west limb. The vertical thick dashed lines show the minimum times of the solar cycles. Full size image Cross-correlation analysis is ...
We study ground-state and thermal pairwise concurrence in one-dimensional frustrated spin- 1 / 2 antiferromagnetic J 1– J 2 model embedded in a uniform magnetic field. Frustration is found to change the magnetic field dependence of concurrence qualitatively. Especially concurrence between second and...
Low temperature measurements show a hard magnetic behavior and the presence of exchange-bias effect after field cooling to 2 K. The results obtained in this study prove essential for the development of flexible electronics.Similar content being viewed by others Phase transition and electrical ...
FAST TRACK COMMUNICATION: Percolation crossing formulae and conformal field theory Using conformal field theory, we derive several new crossing formulae at the two-dimensional percolation point. High-precision simulation confirms these results. Integrating them gives a unified derivation of Cardy's formula...
Scaling of the critical current in ITER type niobium-tin superconductors in relation to the applied field, temperature and uni-axial applied strain The three dimensional surface of the critical current density versus field and temperature J/sub c/(B,T) of niobium-tin is a function of the ...
Extravascular signal decay rate R2 or R2 ∗ as a function of blood oxygenation, geometry, and field strength was calculated using a Monte Carlo (MC) algorithm for a wider parameter range than hitherto by others. The relaxation rates of gradient-recalled-echo (GRE) and Hahn-spin-echo (HSE)...
This equation can be extended to include a second excited crystal field level, but this leads to a highly under constrained fit, with too many adjustable parameters to be reasonably determined by a 1-dimensional data set. In relatively few rare earth magnets, straightforward Curie–Weiss behavior...
A two-dimensional plane model based on the PIC method30 was used to simulate the effects of magnetic fields with different configurations and field strengths on plasma plume acceleration. It is difficult to directly simulate the plasma discharge and the four acceleration modes, so we ignore the ...
