A permanent magnetic field may be employed to change the positions of the stable magnetic orientations of the magnetostrictive nanomagnet.

Contemporary Topics In Semiconductor Spintronics

Collective computational activity in self-assembled arrays of quantum dots: It is usually detected with semiconductor detectors which exhibit a change in their electrical resistance under infrared illumination. The stable state is then monitored by application of A. Dubbed ‘spintronics’, the new technology is expected to one day form a basis for the development of smaller, smarter, faster devices.

Quantum dots are nanoscale structures that have the potential for use as superdense computer data storage media, highly tunable lasers and nonlinear optical devices.

This project is awarded under the Nanoelectronics for and Beyond competition, with support by multiple Directorates and Divisions at the National Science Foundation as well as by the Nanoelectronics Research Initiative of the Semiconductor Research Corporation.

In contrast, a single-domain nanomagnet with uniaxial shape anisotropy, that encodes binary bits in its magnetization orientation, is much more energy-efficient because it is a spin-based switch in which the spins internally interact. With this principle of detection, it is possible to make the resistance change in the detector much larger at room temperature. An international leader in the field of spintronics, Dr. The soft layer of the p-MTJ is magnetostrictive and the strain acts as an effective in-plane magnetic field around which the magnetization of the soft layer precesses to complete a flip.


A magnetostrictive-piezoelectric multiferroic single- or multi-domain nanomagnet whose magnetization can be rotated through application of an electric field across the piezoelectric layer has a structure that can include either a shape-anisotropic mangnetostrictive nanomagnet with no magnetocrystalline anisotropy or a circular nanomagnet with biaxial magnetocrystalline anisotropy with dimensions of nominal diameter and thickness.
