What are spintronics used for?

Spintronics is one of the emerging fields for the next-generation nanoelectronic devices to reduce their power consumption and to increase their memory and processing capabilities. Such devices utilise the spin degree of freedom of electrons and/or holes, which can also interact with their orbital moments.

What are spintronics materials?

Ferromagnetic metals include Fe, Co, Ni metals, and also their alloys. They are the oldest spintronics materials that were used to construct spin valves and magnetic tunnel junctions. These materials are abundant and cheap, and can be handled easily.

Is Spintronics a quantum computer?

Spintronics is a form of electronics based on spin rather than charge. By carefully controlling and manipulating an electron’s spin within a molecule, it turns out we can actually do quantum computations.

Is Spintronics the future?

Spintronics is the alternative future technology, which is based on using the fundamental spin of electron in additions to its charge to carry and store information.

What is the difference between electronics and spintronics?

The magnetic field is generated when electrons flow through wire coils mounted in the drive write heads which move across the face of the platters, changing the alignment of the magneto-sensitive particles on the platter surface. Reversing the electron flow reverses the field; the two directions represent one and zero.

Who invented spintronics?

The history of spintronics Spintronics dates to the 1960s and was discovered by a group at IBM headed by Leo Esaki, a Japanese physicist who would later go on to win a share of the Nobel Prize I 1973 for discovering the phenomenon of electronic tunneling.

What are the developments in spintronics based on?

Spintronics is the new science of computers and memory chips that are based on electron spin rather than (or in addition to) the charge (used in electronics). Spintronics is an exciting field that holds promise to build faster and more efficient computers and other devices.

Why is spintronics better than electronics?

Spintronics has several advantages over conventional electronics. Less energy is needed to change spin than to generate a current to maintain electron charges in a device, so spintronics devices use less power. Spin states can be set quickly, which makes transferring data quicker.

What is spin voltage?

This spin voltage characterizes the tendency of electron spins to diffuse through a material. This communication of spins between electrons creates a wave that makes it possible to diffuse the spin of electrons through even an insulating material without the electrons actually moving.

What is spin flipping in NMR?

When the nuclear magnetic moment associated with a nuclear spin is placed in an external magnetic field, the different spin states are given different magnetic potential energies. This “spin flip” places some of the spins in their higher energy state.
