Abstract: As traditional semiconductor devices reach their limitations in terms of further scaling and integration, spintronic technologies are emerging as a viable alternative. In contrast to charge-based electronics, spintronic devices utilise the electron's spin, providing distinct benefits in terms of low leakage power, high endurance, non-volatility, and speed in read/write operations. These attributes render them extremely desirable in contrast to CMOS equivalents and well-suited for computing requirements, such as big data and the internet of things (IoT). This article offers a comprehensive overview of spintronics evolution in the last two decades, encompassing the underlying physical phenomena - such as spin-orbit driven effects like the spin hall effect, tunnelling magnetoresistance, and device-level applications, including spin valves and spin logic circuits. In addition, the article describes the present status of spintronic research and offers a vision on its future trajectory, highlighting the significance of spintronics to drive next-generation computing and memory technologies.
