have made the first direct observations of free-electron Landau states -- form of quantized states that electrons adopt when moving through a magnetic field -- and found that the internal rotational dynamics of quantum electrons, or how they move through the field, is surprisingly different from ...

Further, examining the phase of the EVB at the image plane in a TEM instrument, i.e., in the far-field, is non-trivial. There are numerous methods to model the contrast present in a defocused TEM image due to the phase shift imparted to the electron beam through interaction with the ...
thereby favouring a chiral Bloch-type wall. Consequently,Htorgives rise to a torsional torque,τtor = −γtorM × Htor, acting onM, whereγis the gyromagnetic ratio. If the volume spin-transfer torque and the anisotropy field torque due to the shape anisotropy of DW are...
Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to lin
magnetic field causes an induced electromotive force that tends to maintain the current and the magnetic field and may cause a spark between the contacts of the switch. The self-inductance of a coil, or simply its inductance, may thus be thought of as electromagnetic inertia, a property that ...
When a magnetic field is applied, some of the unpaired electron spins align themselves with the field and overwhelm the opposite force produced by diamagnetism. However, the effect is only noticeable at very low temperatures, said Daniel Marsh, a professor of physics at Missouri Southern State ...
Gravitational field D. Radiation field Correct Answer B. Magnetic field Explanation Magnetic field is the area around a magnet. The magnetic field is the region around a magnet where the magnetic forces are observable. It is defined by the presence of magnetic force on moving charges, which are...
In the most common type of solar flares, two parallel ribbons appear and move away from each other, which could be related to the reconnection electric field under the theory of two-dimensional (2D) X-point reconnection, opening up a wide field of solar research. Another breakthrough came ...
Here, we derive a general recipe to construct a low-energy Hamiltonian, taking as input only the circuit geometry and the solution of the external magnetic fields. We find that the interplay of geometry and field distribution leads to a much richer circuit dynamics than commonly anticipated, ...
