Abstract

The burgeoning field of spintronics requires the engineering of advanced classes of materials that provide unique magnetic characteristics. This comprehensive literature review explores the considerable utility of three distinct material classes—Complex oxide-based structures—for next-generation spin-based applications. By critically analyzing a diverse body of latest experimental investigations, this article seeks to elucidate the unique benefits found within these materials, including long spin lifetimes, tunable spin transport, and novel effects arising from their fundamental electronic properties. The review further addresses the key hurdles and promising research directions in this highly active fiel

1. Introduction: Beyond Conventional Metallic Spintronics

Traditional spintronic systems have mostly utilized ferromagnetic metal heterostructures such as Heusler alloys and elements such as platinum. While these systems pioneered groundbreaking advances like spin-transfer torque (STT), they often exhibit inherent limitations, such as significant spin memory loss at junctions and difficult control of their magnetic properties. This has propelled the extensive search for novel systems that can mitigate these limitations and unlock new capabilities. This has led to the advent of Complex oxides, which provide a diverse playground for engineering spin dynamics with an exceptional degree of precisio

2. Fundamental Principles and Mechanisms

The underlying basis of VCMA stems from the intricate coupling between spin, orbit, and lattice in crystalline devices. In the case of Spin-Orbit Torque, the key driver is the Rashba-Edelstein Effect (REE). The SHE generates a charge current in a material with strong spin-orbit coupling (e.g., Pt) into a perpendicular spin current, which then applies a torque on the neighboring ferromagnetic layer, possibly reversing its magnetization. Likewise, VCMA functions via the change of electron densities via the use of an charge accumulation at an interface, If you beloved this article and also you would like to collect more info about ignou Mcom project report generously visit our web site. thus lowering the coercivity required for magnetization switching. Meanwhile, Spin Caloritronics deals with the coupling between spin currents and thermal gradients, revealing possibilities for waste heat harvesting and new detection scheme

2. The Promise of Atomically Thin Materials

The isolation of atomically thin crystals heralded a revolution in nanotechnology, and its influence on spintronics has been profound. However, beyond graphene, the class of 2D Van der Waals materials includes a vast array of systems offering intrinsic magnetism, such as hexagonal boron nitride (h-BN). Their defining advantage lies in their ultra-smooth interfaces and weak inter-plane bonding, which allows for the fabrication of pristine heterostructures with minimal mismatch. This article emphasizes latest advances in leveraging these heterostructures for coherent spin transport, electrically controllable spin lifetimes, and the observation of exotic topological states like the skyrmions that are pivotal for energy-efficient quantum computin

4. Complex Oxides: A Playground of Correlated Phenomena

Complex oxide structures constitute a rich and fascinating class of compounds where intense interactions between orbital degrees of freedom lead to an astonishing variety of ground states, including high-temperature superconductivity. This intrinsic complexity makes them a highly promising platform for engineering unconventional spintronic functionalities. The article highlights how the junction between different oxide layers can host a conducting sheet with unique magnetic behavior, such as Rashba spin-splitting. Moreover, the intimate coupling between structural and magnetic orders in magnetoelectric oxides offers the highly sought-after capability to switch magnetization with an voltage rather than a wasteful spin current, a key requirement for ultra-low-power logic application

3. Organic Semiconductors: Towards Flexible and Tunable Spintronics

In sharp opposition to inorganic metallic systems, carbon-based molecules present a entirely unique paradigm of advantages for spintronic devices. Their key strengths include their negligible hyperfine interaction, which potentially leads to ultra-long spin lifetimes, and their synthetic tunability, which enables for the tailored optimization of spin characteristics through chemical synthesis. Additionally, their solution processability paves the way for the realization of conformable and inexpensive electronic applications. This part of the review critically discusses the progress in understanding spin relaxation mechanisms in polymeric devices, the role of interface quality, and the promising concept of molecular spintronics, where the chiral structure of films enables the filtering of electrons based on their spin orientation, a effect with significant consequences for spin detection without ferromagnetic contact
