Magnetoresistive Devices for Next-Generation Electronic Applications

Abstract

Magnetoresistive devices have emerged as essential components in modern electronic systems due to their ability to convert magnetic signals into electrical resistance changes. These devices exploit magnetoresistance effects such as anisotropic magnetoresistance (AMR), giant magnetoresistance (GMR), and tunneling magnetoresistance (TMR) to achieve high sensitivity and efficient data processing capabilities. In recent years, magnetoresistive technologies have been widely applied in data storage systems, magnetic sensors, and emerging spintronic devices. The integration of nanostructured magnetic materials and multilayer thin-film architectures has significantly improved device performance, enabling faster switching speeds, lower power consumption, and enhanced scalability. This article explores the fundamental principles of magnetoresistive effects, device architectures, fabrication techniques, and their applications in next-generation electronics. It also discusses the challenges associated with material stability, thermal management, and large-scale manufacturing. Future research directions emphasize the development of novel magnetic materials and integration with advanced semiconductor technologies to enable high-performance computing, IoT systems, and energy-efficient memory solutions
