Not exact matches

A device that slides magnetic bits back and forth along nanowire «racetracks» could pack data in a three - dimensional microchip and may replace nearly all forms of conventional data storage

By applying a magnetic field to semiconducting nanowires laid across a superconductor, you can move electrons along these wires, creating two points in space that each mimic half an electron.

In essence, it proves that electrons on a one - dimensional semiconducting nanowire will have a quantum spin opposite to its momentum in a finite magnetic field.

Previously it has been shown that the chirality can be manipulated by applying magnetic fields to complicated nanowire geometries, but the use of magnetic fields is wasteful of energy and limits the ability to address individual domain walls selectively.

An electric current can do the trick; as an electron crosses a domain wall and feels its own magnetic pointing, or spin, flipped from one orientation to the other, it forces an atom within the nanowire to flip magnetic orientations as well to compensate.

Small magnetic domain wall structures in nanowires can be used to store information and, for example, can be used as angle sensors.

A team of researchers at the Brazilian Center for Physics Research is studying the motion of vortex domain walls — local regions of charge that collectively store information via their configuration — driven by magnetic fields in ferromagnetic nanowires, which are configured in a straight line with an asymmetric Y - like branch.

They found that the nanowires should generate a magnetic field as an electrical current passes through the atoms, just as larger conductive coils, known as solenoids, do.

Bulk nanoscale technologies were used to create three - segment nanowires of gold and nickel, and magnetic bearings of gold, nickel, and chromium.

The most obvious approach would be to apply a magnetic field in the direction in which the magnetization runs in the tiny nanowires.

When a nanowire made from a semiconductor is connected to a superconductive material, researchers see a so - called zero - bias peak in the case of certain magnetic fields and electrical charge.

Without taking particular care of the chemical potential in the nanowire, we observe supercurrent oscillations at finite magnetic field.
