The loops become smaller and closer together as the electron moves farther and farther into the high-field region. Eventually, a point is reached beyond which the electron cannot penetrate. At this point (called the mirror point), the particle is reflected—in much the same way that a ball ...
revealed when magnetic fields (H) suppress superconductivity in underdoped cuprates has been a longtime mystery. Surprisingly, the high-field behavior of the resistivity observed recently in charge- and spin-stripe-ordered La-214 cuprates suggests a metallic, as opposed to insulating, high-field ...

In this case, the magnetic fields created by those spins point in opposite directions, so they cancel each other. However, some atoms contain one or more unpaired electrons, and these unpaired electrons create a tiny magnetic field. The direction of their spin determines the direction of the ...
From point of view of physics, the answer is the following. Considering the cell as a droplet of diamagnetic liquid placed in a non-uniform magnetic field, one can conclude that such a droplet will divide itself into several smaller drops to satisfy the minimum of the total system energy. ...
One key point of the better application of permanent magnetic technology is the generation of magnetic field with stronger intensity and more even distribution using less magnet. In this study, the permanent magnetic field under varying arrangement, thickness, number, and arc degree of magnets was ...
Anisotropy of the quark-antiquark potential in a magnetic field We investigate the static Q Q potential for N f = 2 + 1 QCD at the physical point in the presence of a constant and uniform external magnetic field. The... C Bonati,M D'Elia,M Mariti,... - 《Phys.rev.d》 被引量:...
magnetic field strength. the direction of the magnetic field at a point is taken as the direction that a north pole would tend to move if it were at that point The forces increase as poles get closer together. The Earth's magnetic field ...
Up to this point, everything is exact and no assumptions about the relative magnitudes of the different components of the flow and field, or the length scales on which they vary. However, the equations are very complicated, and to get a system which we can understand we must make ...
In this Letter, we show how the magnetoplasmonic crystal can operate as a highly sensitive local sensor of DC magnetic field. The use of controllable AC magnetic field allows one to choose the certain region at the magneto-optical response curve with the strongest dependence of the signal on ...
