Overview

"Noise is defined as the random fluctuations in a physical quantity. In electronic devices, this quantity is the voltage or the current at any port of the device. In general, the random nature of this inherent noise in electron transport comes from the thermal motion and intrinsic properties of the building blocks of solids. Measuring noise can be an incredibly rich source of information about the microscopic properties of spintronic devices that are often not accessible by other techniques. While the characteristic dimensions of electronics keep getting smaller, the signals with which devices operate become noisier. Of late, the spin degree of freedom has become an important ingredient of modern electronics. The ""coin"" of noise phenomena has two sides: the information one can obtain from noise (""Noise is the signal,"" according to Rolf Landauer, one of the founders of modern quantum electron transport theory) and the need to understand and control the noise in nanoscale devices subject to spin-, charge-, and nucleus motion-related stochastic processes not only at room but even at very low temperatures. This book covers the main physical mechanisms and the different contributions (1/f noise, shot noise, etc.) behind electronic fluctuations in various spintronic devices. It presents the first comprehensive summary of fundamental noise mechanisms in both electronic and spintronic devices and is therefore unique in that aspect. The pedagogic introduction to noise is complemented by a detailed description of how one could set up a noise measurement experiment in the lab. A further extensive description of the recent progress in understanding and controlling noise in spintronics, including the boom in 2D devices, molecular spintronics, and field sensing, is accompanied by both numerous bibliography references and tens of case studies on the fundamental aspects of noise and on some important qualitative steps to understand noise in spintronics. Moreover, a detailed discussion of unsolved problems and outlook make it an essential textbook for scientists and students desiring to exploit the information hidden in noise in both spintronics and conventional electronics."

Author Information

Farkhad G. Aliev is a professor of condensed matter physics at the Faculty of Science, Universidad Autonoma de Madrid (UAM), Spain. He teaches undergraduate and graduate courses on mathematics and physics. Prior to this, he conducted research as scientist at M.V. Lomonosov Moscow State University, Moscow, Russia (1984-1995), and as visiting professor at UAM (1990-1995) working in the field of heavy fermion and high-Tc superconductivity and thermoelectric properties of half-Heusler compounds. His focus shifted to spintronics and nanomagnetism since 1995 during his stay as research professor at Katholeike Universiteit Leuven, Belgium. Currently he leads the MAGNETRANS group created at UAM in 2001 which focuses on experimental studies of noise and magnetization dynamics in magnetic nanostructures. His research interests also include vortex dynamics in superconductors and lateral photovoltaic effect in ferromagnet/semiconductor patterned structures. He is co-author of more than 150 publications referenced in ISI-WEB and 4 patents and co-editor of a textbook. He has directed 9 PhD theses, has been publication editor of Magnetism and Magnetic Materials (MMM2016) conference proceedings and is on the editorial board of Scientific Reports. Juan Pedro Cascales is a postdoctoral researcher at the Francis Bitter Magnet Laboratory at the Massachusetts Institute of Technology (MIT). He obtained his PhD in condensed matter physics and nanotechnology from the Universidad Autonoma de Madrid, Spain, in 2015 under the supervision of Prof. Farkhad Aliev. His research centers around the investigation of the fundamental aspects of electron transport in various types of spintronic devices, combining magnetic, topological insulator, organic and/or superconducting materials by thin-film evaporation and the study of conductance and voltage fluctuations (or noise) at cryogenic temperatures. He has co-authored 15 publications that are referenced in ISI-WEB and 1 patent.
