Manipulating the magnetization of materials on extremely short time scales, in the picosecond range, is a highly coveted grail for information technologies. The complex magneto-optical techniques currently used are difficult to integrate spintronics into devices. To overcome these constraints, Juan Carlos Rojas-S\u00e1nchez<\/strong> of the Institut Jean Lamour (CNRS\/Universit\u00e9 de Lorraine)<\/a> and one of the PIs of the ULTIMATE-I project has received an ERC Consolidator grant for his Magnetallien project<\/strong>.<\/p>\n\n\n\n

In spintronics, components are controlled by a quantum parameter of electrons: the spin. This approach promises much more powerful and energy-efficient integrated circuits and components but faces many technical challenges.<\/p>\n\n\n\n

“To achieve this goal, I am interested in materials where there is a strong coupling between spin and orbit,” explains Juan Carlos Rojas-S\u00e1nchez, a CNRS researcher at the Institut Jean Lamour (CNRS\/Universit\u00e9 de Lorraine). For example, when an electric current is passed through a platinum nanowire, it scatters the electrons in opposite directions according to their spin orientation, creating a spin current that can be injected into an adjacent magnetic layer. This phenomenon has applications such as memories, sensors or the realization of logic circuits.<\/p>\n\n\n\n

Different approaches are envisaged to study and control this key ingredient: the spin-orbit coupling. For example, by generating a spin current in a thin layer of magnetic material and injecting it into a neighbouring layer. Understanding and exploiting this phenomenon on the picosecond time scale remains a challenge. It is currently only possible to obtain a signal of up to a hundred gigahertz using lasers and particularly “heavy” optical means,” notes Juan Carlos Rojas-Sanchez. I want to reduce the cost and size of the devices by exploiting new physical systems that use spin-orbit interaction.

To this end, he has set up the MAGNETALLIEN project, for which he has just been awarded this ERC Consolidator grant.<\/p>\n\n\n\n
