Spintronics is basically a part of semiconductor which deals with the electron spin and magnetic moment in addition to its original charge in the electronic devices. It does not require electricity to perform its function. The gadgets that use spintronics are more compact and long lasting than other normal electronic devices. This property of electron (spin) is recognized as the magnetic field. It is an emerging technology that finds application in the area of communication, memory and storage devices. In this article, a detailed study on the basics, applications …show more content…

Introduction:
The term “Spintronics” is self-explanatory that examines the spin of the electrons in the devices. The spin of an electron is defined as the electric and magnetic field angular momentum of an electron. Each electron’s spin is aligned in only two directions. They are “upward” and “downward”. Spintronics employs magnetic materials and it consists of magnetic connection at the two ends and a non-magnetic contact in between them. In agreement with a lecture [10], the dominant prerequisites for spintronics are spin relaxation, spin injection and spin detection. Spin relaxation is defined as an act of bringing the unstable electrons into a state of stability. The process of fetching a spin momentum and velocity from a ferromagnetic material to a semiconductor or a non-ferromagnetic substance. Spin detection is the method of finding the exact spin of the electron particles in the device. These three concepts are the major principles of spintronics. The information is represented as bit in the form of spin of an electron. One …show more content…
The scientific fact which governs the spin of the electron is that any pair of adjacent electrons tends to lie in the reverse direction i.e., opposite of each other and the adjacent electrons are only allowed contact with one another. According to a journal [6], the spintronics works due to the interaction of the adjoining electrons and their resultant motion in a specified direction. There are some rules pertaining to the direction of the electrons. When two electrons lie in the ascending direction, then the spin of the electron is assumed as ‘1’. When two electrons lie in the descending direction, then the spin of the electron is assumed as ‘0’. In the presence of a feeble magnetic field, when one electron lies in the ascending direction and the other electron lies in the descending direction, then the resultant electron is finally upward directed. The final conclusion about its functionality is that when both the electrons lie in the same direction in the presence of a feeble magnetic field, then the resultant electron is downward directed. These rules form the basics of spintronics. Following an article [7], it is stated that the spin of the electrons can be oriented in different ways. They can be grouped in a random manner, either with each of their spins aligned in a dissimilar direction or all the spins oriented in a similar direction. In a spintronics device like spin
