The writing in conventional magnetic memories based on magnetic tunnel junctions (STT-MRAM) is intrinsically stochastic : a large amplitude thermal fluctuation is required to trigger the siwthing of the storage layer magnetization. SPINTEC has shown that this stochasticity can be almost completely suppressed by inducing an oblique anisotropy (easy-cone anisotropy) in the storage layer. This […]

A CoFe based ferromagnetic alloy has been used in lateral spin valves to replace NiFe alloys, which are overwhelmingly exploited as ferromagnets electrodes in lateral spintronic devices. By using this second material, emitted signals are found to be one order of magnitude larger. In addition to using the electric charge of the electron, spintronic technologies […]

Bringing a ferromagnetic layer to resonance creates non-equilibrium magnetization dynamics which generates a spin current. The spin current propagates from the ferromagnet into a neighboring layer if permitted by the interface. This is equivalent to saying that the air-flow generated by rotating the blades of a fan can propagate in a neighboring room if the […]

Ces structures magnétiques nanométriques ont été observées à températures ambiante dans des matériaux compatibles avec l’industrie électronique. Ces résultats font sauter un verrou important quant à l’utilisation des skyrmions comme vecteur d’information à l’échelle nanométrique dans nos ordinateurs.

Overview Materials development is a fundamental activity at SPINTEC, a determining factor for the success of our research projects. The Materials Growth team assists and participates on the development and characterization of new materials and stacks for the different research projects. Sputtering and molecular beam epitaxy (MBE) are our two main deposition techniques. The team […]

Spintec has developed a strong expertise in the fields of temperature-dependent magnetic and transport properties, sub-nanosecond magnetization dynamics, high frequency noise and near field magnetic probing. The laboratory is equipped with numerous experimental set-ups, whether home made or commercial, which allow characterizing any system from the laboratory sample to the wafer-level test device. Pictures show […]
