STAY UP TO DATE ON THE STATE OF MRAM TECHNOLOGY AND ITS APPLICATIONS WITH THIS COMPREHENSIVE RESOURCE Magnetic Memory Technology: Spin-Transfer-Torque MRAM and Beyond delivers a combination of foundational and advanced treatments of the subjects necessary for students and professionals to fully understand MRAM and other non-volatile memories, like PCM, and ReRAM. The authors offer readers a thorough introduction to the fundamentals of magnetism and electron spin, as well as a comprehensive analysis of the physics of magnetic tunnel junction (MTJ) devices as it relates to memory applications. This book explores MRAM's unique ability to provide memory without requiring the atoms inside the device to move when switching states. The resulting power savings and reliability are what give MRAM its extraordinary potential. The authors describe the current state of academic research in MRAM technology, which focuses on the reduction of the amount of energy needed to reorient magnetization. Among other topics, readers will benefit from the book's discussions of: An introduction to basic electromagnetism, including the fundamentals of magnetic force and other concepts An thorough description of magnetism and magnetic materials, including the classification and properties of magnetic thin film properties and their material preparation and characterization A comprehensive description of Giant magnetoresistance (GMR) and tunneling magnetoresistance (TMR) devices and their equivalent electrical model Spin current and spin dynamics, including the properties of spin current, the Ordinary Hall Effect, the Anomalous Hall Effect, and the spin Hall effect Different categories of magnetic random-access memory, including field-write mode MRAM, Spin-Torque-Transfer (STT) MRAM, Spin-Orbit Torque (SOT) MRAM, and others Perfect for senior undergraduate and graduate students studying electrical engineering, similar programs, or courses on topics like spintronics, Magnetic Memory Technology: Spin-Transfer-Torque MRAM and Beyond also belongs on the bookshelves of engineers and other professionals involved in the design, development, and manufacture of MRAM technologies.

In the last few decades, due to the dramatic improvement of the TMR (tunneling magnetoresistance) effect in MTJs (Magnetic Tunnel Junctions), the data storage industry has been revolutionized. There are so many applications based on this technology, e.g.: read head in hard disk drives; magnetic sensors, etc., while its most advanced application nowadays is on the Magnetoresistive Random Access Memory (MRAM), a type of nonvolatile, high speed, high density, yet low power consumption memory - often termed the "universal memory" [1]. For most applications, magnetic tunnel junctions are fabricated with thin film technologies. In industry, they are mostly deposited by magnetron sputtering for mass production purposes. While in research laboratories, MBE (Molecular Beam Epitaxy), PLD (Pulsed Laser Deposition), and E-beam (Electron beam physical vapor deposition) are often used to deposit well-controlled, high quality layers. The very core component of an MRAM cell is an MTJ, which possesses the desired TMR effect. An MTJ basically consists two ferromagnetic materials separated by a thin insulator. Typically, the connection across the insulating layer is what we call a junction, and the layer is usually a few nanometers thick, which ensures that the junction is thin enough to let the electrons tunnel from one side of the insulator to the other. This is a purely quantum mechanical phenomenon and will be forbidden in classical physics because classically an insulator cannot conduct. In this thesis, we demonstrated the epitaxial growth of the tunnel junctions FeCo/MgO/EuS/Ti on MgO-buffered Si (100) wafers, and showed that TMR in these junction reaches up to 64% at 4.2K. We also discovered how different thicknesses of MgO and measurement temperatures affect the TMR of these junctions. We then optimized the growth conditions of the junctions, and used XPS (X-Ray Photoelectron Spectroscopy) to analyze their chemical characteristic features. The best TMR occurring at 1nm MgO thickness is a result of the competition between symmetry enhancement through MgO, and thickness induced multistep hopping.

Over two volumes and 1500 pages, the Handbook of Spintronics will cover all aspects of spintronics science and technology, including fundamental physics, materials properties and processing, established and emerging device technology and applications. Comprising 60 chapters from a large international team of leading researchers across academia and industry, the Handbook provides readers with an up-to-date and comprehensive review of this dynamic field of research. The opening chapters focus on the fundamental physical principles of spintronics in metals and semiconductors, including an introduction to spin quantum computing. Materials systems are then considered, with sections on metallic thin films and multilayers, magnetic tunnelling structures, hybrids, magnetic semiconductors and molecular spintronic materials. A separate section reviews the various characterisation methods appropriate to spintronics materials, including STM, spin-polarised photoemission, x-ray diffraction techniques and spin-polarised SEM. The third part of the Handbook contains chapters on the state of the art in device technology and applications, including spin valves, GMR and MTJ devices, MRAM technology, spin transistors and spin logic devices, spin torque devices, spin pumping and spin dynamics and other topics such as spin caloritronics. Each chapter considers the challenges faced by researchers in that area and contains some indications of the direction that future work in the field is likely to take. This reference work will be an essential and long-standing resource for the spintronics community.

The Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST) is dedicated to three fundamental and complementary tasks: (1) increase the accuracy of our knowledge of the physical parameters that are the foundation of our technology-driven society; (2) disseminate technologies by which these physical parameters can be accessed in a standardized way by the stakeholders; and (3) conduct research at both fundamental and applied levels to provide knowledge that may eventually lead to advances in measurement approaches and standards. This report assesses the scientific and technical work performed by the PML and identifies salient examples of accomplishments, challenges, and opportunities for improvement for each of its nine divisions.
