Magnetic Nano- and Microwires

Magnetic Nano- and Microwires: Design, Synthesis, Properties and Applications, Third Edition presents the state of the art in research on the curvature of magnetic nanostructures, a topic where observed novel phenomena form the basis of a number of many new applications.

Part I explores advanced designs and techniques for the synthesis, growth, and processing of cylindrical magnetic nanowires, nanotubes, and their arrays, as well as of nanowire heterostructures. Methods such as electrodeposition, atomic layer deposition, focused-electron/ion-beam-induced deposition, epitaxial growth by chemical vapor transport or ultrarapid solidification are covered. The engineering of anodic membranes as templates for electrochemical patterning and of modulations of nanowires is also discussed.

Part II addresses the magnetization processes and derived properties of curved magnetic nanostructures. This includes arrays of cylindrical nanowires, and in particular also considers individual nanowires where the effects of curvature together with compositional and diameter modulations are observed. Helical and exotic vortex-transverse complex domain configurations and skyrmion tubes are investigated together with Bloch point domain walls and complex rotational mechanisms involved in the remagnetization processes, in addition to magnetotransport properties and the action of electrical current pulses.

Part III focusses on emerging applications of nano- and microwires. It reviews applications where nanowire arrays are used or proposed, including magnetocaloric, thermoelectric for spin caloritronics and thermopower, magnetostrictive sensors and transducers, and biomedical and oncological applications such as robotics and swimmers. A number of devices that makes use of magnetic microwires as sensing elements are also discussed, including advanced flux-gate field sensors, microwave and electromagnetic shielding devices, and tunable magnetic hybrid composites.
