A Magnetic Field Gradient refers to the modification of the main magnetic field in a linear manner within the magnet bore, creating variations in the magnetic field with spatial position. These gradients are denoted as G x, G y, and G z, and are generated by gradient coils to allocate spat...
Thermally activated flux motion has been studied in c-axis oriented epitaxial YBa2Cu3O7−δ thin films with a critical current density Jc of 4 × 106 A/cm2 at 77 K in the absence of an external magnetic field. The magnetoresistivity and the critical current density were measured in appli...
We also state the unsolved questions in this fascinating open problem of cosmology and propose future observations to address them. )after a few Hubble times this very turns into=∗(/∗
For a time-varying magnetic field, there immediately emerges the resulting electric field due to the first London equation, E = μ0λ2∂tj. Let us say a couple of words about the nature of this electric field. Due to current conservation ∇ ⋅ j = 0, so the ...
due to the formation of the SkT structure by field cooling, producing a pinned metastable state which relaxes over the first few field increments, before displaying the expected increase indssat higher applied fields. Such pinning effects are not considered in the simulation model. In the future,...
particle size is within the single-domain size range for magnetite, and dipolar interactions between the particles result in alignment of the magnetic moments, such that the chain of particles forms a magnetic compass needle, which enables the bacteria to navigate in the Earth’s magnetic field [...
Even though it is weaker than that at the early stage of the universe, the magnetic field produced in RHIC and/or LHC has been strong enough to influence the strong interaction matter significantly [36]. The effects of the mag- netic field on the masses of hadrons and weak decay ...
FIELD: magnetic measurements; flux-gate magnetometers. SUBSTANCE: device has flux gate with copper-wire metering winding and field winding connected to generator outputs, amplifier- converter unit with resistor in feedback circuit connected to first input of measuring unit and to resistive voltage divi...
In a magnet exhibiting a non-coplanar spin arrangement (black arrows), the local scalar spin chirality between the triplets of spins can be interpreted as an effective magnetic fieldwhich gives rise to a so-called topological orbital moment(TOM, blue arrows) generated by the orbital current of ...
The sensor measures the DC magnetic field component parallel to the AC magnetic field while the shift of optical beam reveals the magnetic field distribution in the desired volume. The enhanced TMOKE, achieved due to excitation of SPPs, allows us to detect the magnetic field with sensitivity ...
