Methods for the Syntheses of Perovskite Magnetic Nanomagnets
Published in Ram K. Gupta, Sanjay R. Mishra, Tuan Anh Nguyen, Fundamentals of Low Dimensional Magnets, 2023
Spintronic devices work on the spin of an electron (the intrinsic angular momentum of an electron) to carry, process, and encode information. These new devices have the advantages of nonvolatility, high data-processing speed, low electric power consumption, and increased integration densities in comparison with conventional semiconductor devices that work on the electronic charge. It is envisioned that adding the spin degree of freedom into the conventional semiconductor devices or the use of a spin degree of freedom alone will add much more capability and enhanced performance to the electronic products. The merging of spintronics with electronics, photonics, and magnetics will ultimately lead to new spin-based multifunctional devices such as spin transistors, spin FETs (field-effect transistors), spin LEDs (light-emitting diodes), spin RTDs (resonant tunneling devices), and spin modulators.
Impact of Nanoelectronics in the Semiconductor Field
Published in Shilpi Birla, Neha Singh, Neeraj Kumar Shukla, Nanotechnology, 2022
The research and application of electron spin, as well as its related magnetic moment and electric charge, is known as spintronics. Since spintronics is focused on the spin of individual electronics rather than the charges of several electrons, systems based on this area of research are supposed to have significantly higher computing efficiency and lower power consumption. Spintronics is also important in a variety of technologies that use quantum behavior for computation [3].

Spintronics is a new technology in electronics which harnesses both the spin and charge of electrons to carry and store information for device functionality. The technology combines the functions of the modern semiconductor microelectronics and magnetic storage devices in a single chip. The importance of the spintronics technology includes providing high speed, high power lasers, lower threshold current, high-density logic, low power, high electronic memory devices, and optoelectronic devices [1]. The technology has made it possible to develop nanoelectronics (small devices), which largely depends on the growth of spintronic materials. So far, spintronics is showing significant progress and many advantages leading to the development of new spintronics materials and becoming a promising field in memory and data storage requirements. Additionally, more interest has been developed in this area because of the capability to develop various new devices that combine sensor, logic, and storage applications. With this technology, small devices with huge storage and faster transmission of data can be developed.

Spintronic devices, an example application of magnetic multilayers, are energy-saving and high-density memory devices that can contribute to the information society in the near future. In recent years, the development of magnetoresistive random access memory has progressed rapidly, and there is high demand for the development of novel ferromagnetic materials with large MCA [3]. To date, L10-type ordered alloys with 2-element, 2-layer periods have been developed; L10-FePt is a typical example, and recently, L10-FeNi has been widely investigated theoretically and experimentally [4–7]. At present, L10-type magnetic materials are based on two elements, and few studies have been conducted to extend the number of elements and their periodicity. Despite the ongoing investigation on ternary multilayer materials, the candidates explored thus far are few, leaving considerable space for further investigation [8–10].

Dilute magnetic semiconductors (DMSs) have recently attracted the interest of the researchers to a great extent in recent times accounting for their exceptional magnetic properties and versatile applications in the field of spintronic devices.[1,2] Hence, a wide variety of semiconductor devices, such as lasers, spin-polarized light-emitting diodes and spin-transistor logic devices can be designed. The main idea of spintronics is to use both the charge and spin of electrons at the same time in order to enhance the performance of microelectronic devices of nanometer size. This type of devices requires materials with ferromagnetic ordering at operational temperatures compatible with the existing semiconductor materials. This device concept will be well suited by DMSs.[3]

A modern electronics technology called spintronics has attracted considerable interest in data processing for magnetic memory devices applications, ultra-high density information storage and longer-term design of new electronic components [1]. Spin (or spintronic) electronics [2] exploits the magnetic spin of electron for the technology of electronics devices; it is originated from the discovery of giant magnetoresistance [3, 4]. Spintronics technology is focused on the simultaneous control and manipulation of the electron charge as well as its magnetic moment (spin) in order to realise substantial applications in memory devices and sensors to improve the performance of new logical and information storage devices [2, 5]. The expected benefit of spintronics over conventional electronics would be non-volatility, increased data processing speed, increased transistor density and reduced power consumption [6].
