The conversion of a conventional charge current into a spin current, carrying not charges but angular momentum, can be done in non-magnetic systems using the spin-orbit coupling. Spin-dependent transport effects can thus be observed in very wide ranges of materials and interfaces, allowing spin manipulation in metals, oxides [1], semiconductors, Rashba interfaces, topological insulators, 2D […] >>

Electron Holography is an advanced technique of Transmission Electron Microscopy that consists in reconstructing the full electron wave to access its phase. The phase of an electron wave is modulated by the presence of electro-magnetic fields that may be quantitatively mapped, once the phase is obtained. Beyond the possibility of describing magnetism (and more particularly […] >>

Magnetic non-volatile memory (MRAM) is a technology being developed at Spintec. This type of memory associates non-volatility with fast switching of the order of ns. Switching the magnetization direction the storage layer results in cell resistance changes that can be greater than 100%. This switching depends on the application of a current pulse and also […] >>

Applications in artificial intelligence architectures require cell elements that can take multiple states based on different cell inputs. Hardware realizations of such elements can also be realized on magnetic non-volatile memory (MRAM) cells. This technology being developed at Spintec, associates non-volatility with fast switching of the order of a few nanoseconds. In conventional binary memory […] >>

Spintronics, or spin electronics, revolutionized the field of magnetic data storage in the 1990’s thanks to the manipulation of spin properties of devices instead of, or in addition to, charge degree of freedom. Spintronics was triggered by the discovery of Giant Magnetoresistance and led to a new generation of hard disks for data storage, of […] >>
