摘要： A spintronics element comprises two ferromagnetic layers without a non-magnetic interlayer between them. The two ferromagnetic layers may be independently switched by various means such as but not limited to applying one or more external magnetic fields, and/or employing current induced switching, and/or applying optical spin-pumping.

摘要： A spin-valve structure is provided, illustrating the layer structure used for the magnetic tunnel junction, by a method comprising the steps of providing a substrate, growing a ferromagnetic layer on the substrate, growing a tunnel barrier layer on the ferromagnetic layer, providing a first non-magnetic metallic contact on the ferromagnetic layer and providing a second non-magnetic metallic contact for the single ferromagnetic layer. Beside such a single sided structure a double-sided structure can be provided having e.g. a Ga0.94Mn0.06As/undoped GaAs/Ga0.94Mn0.06As trilayer structure on top of a semi-insulating GaAs substrate and an undoped LT-GaAs buffer layer. There is an inner square contact and a surrounding electrical back contact. This sample structure makes it possible to perform two-probe magnetoresistance measurements through both ferromagnets and the GaAs tunnel barrier. The resistance of the device is fully dominated by the vertical tunneling process through the tunnel barrier.

摘要： A semiconductor magnetic body comprises a layer (11 15) intended to trap electrons, wherein said layer (11 15) is surrounded on both sides by a magnetic layer (16, 17). This leads to the creation of ferromagnetic character in spatially limited regions of electronic elements such as but not limited to quantum dots, where this creation is achieved using magnetic materials which do not compositionally form part of the region but are rather contained in the zone or zones adjacent to the region.

摘要： An element for use in an electrical circuit includes sub-region (11) and a second sub-region (12), which regions can contain a charge carrier gas (6) at least during operation and are separated from one another by an insulation zone (13). The insulaton zone (13) is locally interrupted by a barrier zone (15) which presents a potential barrier to the charge carriers. The first sub-region (11) is provided with a first connection (21) for deriving the potential from it. The second sub-region (12) is provided with two connections (22, 23) by means of which a current (I) can be passed through the second sub-region (12). The potential of the first sub-region (11) is found to be proportional to at least substantially the square of the current (I) passed through the second sub-region. This renders the element particularly suitable for an electrical circuit in which such a proportionality is desired.

摘要： A novel and efficient method for polarization conversion, particularly from linear polarization to circular polarization, and, importantly, vice versa, is obtained using shapeanisotropic self-assembled quantum dots, which, having the advantage of extremely small size (nanometer scale), may be readily incorporated into photonic crystals and/or other optical components. Such devices also have the advantage of working in the absence of an applied magnetic field. Such devices also, when a voltage bias is applied, can be used to manipulate electron spin by manipulating light polarization in the same circuit, and vice versa. This permits a high degree of control for either or both of these in spintronics and/or optical devices, the biased quantum dot being used as a nanometer scale electro-optic modulator. Components utilizing the method and/or devices may be used as part of highly compact optical computing networks and/or spintronics systems for e.g., information processing, quantum computation, holography, and data recording.
