Spintronics mainly refers to the study that deals with nuclear's role. It can also be called the role of an electron in a solid-state. This electronic device exploits the properties of spin along with the freedom of charge degrees. It is also named spin Flextronics. This kind of technology intrinsically studies the spin of electrons and it can be seen that magnetic moment is also associated with it.
What is Spintronics?
It is a great technological device and it is known as the spin electrons. The study is related to the intrinsic spin of the electron. The magnetic moment is an important part of this field and that is why it is known as magneto electronics (Sierra et al. 2021). It is an advanced technological field that is new in the research field. It deals with the matter of storage data and it is helpful in the industrial fields. Therefore, it is said that Spintronics mainly refers to the emerging solid-state device technology.

Approaches of Spintronics
- The spin of an electron is controlled by external magnetic fields and by the polarized electrons. These factors also control the electric current. Its main aim is to manipulate the magnetism of electrons.
- It provides versatility and functionality to the products which emerge in future (Researchgate, 2022). The main approaches to this factor are- Semiconductor Spintronics and Metal-based Spintronics.
- The first one manipulates dynamics in a spin and provides probabilities and non-magnetic materials. This helps to develop the technology and it is based on magnetic semiconductors. Metal-based Spintronics mainly goes for giant devices. The current is pass-through the material namely, ferromagnetic.

Applications of Spintronics
It is a common field for storing data in the mass storage device as it has a great capacity to store data in a small area. This kind of device is an ancillary to digital electronics. The most common example of this matter is a hard device (Ibm, 2022).
It is an effective tool and it helps to detect cancer. It is used as spin polarisers and spin valves. ESR or Electron spin resonance is used in Physics and Chemistry. It is seen that the computers that are based on the spin are a developed one which is used in limiting manometer distance.

Importance of Spintronics
Spintronics is a trending as well as an essential research area and it has high potential and capability. This device provides high power lasers, high speed, high-density logic, lower threshold current, electronic memory devices, low power, and optoelectronic devices (Phys, 2022).
This technology is greatly used in many fields and it is an immense source of the circular polarized light. This is the importance of this technology and it helps in various electronic matters. The device has its own works and it uses different electronic properties. It can seem that this process uses the properties for processing, sorting, and transforming information.
Difference between Electronics and Spintronics
Electronics are mainly based on the measurement of the tiny electrical charge of the electrons which is passing through the electronic circuits. An alternative approach for this is Spintronics.
It mainly relies on fundamental quantum-mechanical properties and not the charge of electron (Nature, (2022). Spintronics, on the other hand, can be described as the spinning of Earth on its own axis during the time of rotating around the sun.
The main factor is that the electron also moves around its own axis during the time of rotating around an atom's nucleus. After having all the differences, it is seen that both have developed features and both of them have used different materials.
Future of Spintronics
It is seen that Spintronics has its own application in scientific research and industrial applications. This has a fascinating impact on both fields and it has a great future. It is seen that the electron spin has many untapped potentials which can be explored in the future (Sierra et al. 2021).
This process has a great impact on the Earth it will be a significant progress. The progress is done gradually and is conducted by technology and science of Spintronics. The important factor here is that the world is gradually turning toward spin electronics from then traditional electronics. Different properties like electrical, optical, and revolutionary help in the creation of a new generation of Spintronics devices.
Spintronics is also known as the spin electrons and it is the study of the role which is played by an electron’s spin in the solid-state of physics. Flextronics means the study of intrinsic spin and that is why it is known as the spin Flextronics. These factors are associated with a magnetic moment. It is seen that Spintronics does help in the creation of a prototype device. It is used in the industrial field for the storage of memory. It has its various applications and the most common use is seen in the industrial field.
Q1. How does the measurement of Spin can happen?
The measurement o spin is nothing but the polarisation of a photon. It is seen when a single photon is measured with the help of linear polarization, then it gets aligned with the axis.
Q2. What does it mean by spin-polarized current?
Spin polarization, means the degree to which the elementary particles and their intrinsic angular momentum are aligned to a specific direction. It mainly functions in the ferromagnetic metals like iron.
Q3. What is meant by the Spintronics Device?
It is a specific area and new in the field of development, research, and analysis. It is a combined science of magnetism and electronics. The main aim of this technology is to develop new devices and new functions through quantum characteristics of electrons.
