We have developed arrays of innovative magnetic nanotweezers or “nanojaws” on silicon wafers, by a top-down approach using the fabrication techniques of microelectronics. The mechanical manipulation of micro- and nanometric objects relies on constantly evolving techniques, which are of great interest to the life sciences and biotechnologies. Numerous biomedical studies, either fundamental or applied to […]

Amalio Fernandez-Pacheco, Robert Streubel, Olivier Fruchart, Riccardo Hertel, Peter Fischer, Russell P. Cowburn, Nature Comm. 8, 15756 (2017) Magnetic nanostructures are being developed for use in many aspects of our daily life, spanning areas such as data storage, sensing and biomedicine. Whereas patterned nanomagnets are traditionally two-dimensional planar structures, recent work is expanding nanomagnetism into […]
Read moreGiant and tunable spin-charge conversion at oxide interfaces (April 14th, 2017)
At the interface between the strontium titanate and the lanthanide aluminate forms a 2 dimensional electron system. By using a dynamical spin injection technique, we were able to demonstrate a record conversion yield between spin and charge current in this system, moreover that is tunable in amplitude and sign by an electrostatic gate, a premiere.

We have fabricated large-scale two-dimensional transition metal dichalcogenide (2D TMD) MoSe2, a promising candidate for electronics, valley-spintronics and optoelectronics, on insulating sapphire and have investigated its structural and transport properties. We have shown that the layered MoSe2 exhibits characteristics of a stoichiometric 2H-phase, a van der Waals epitaxy regarding the substrate and we have evidenced […]

We have created an analytical model of spin waves in microscopic spin-wave waveguides in the presence of interfacial Dzyaloshinskii-Moriya interaction. By comparing to micromagnetic simulations, we have demonstrated that spatially periodic excitation sources can be used to create a uni-directional spin-wave-emission source whose properties can be predicted by our model. Since miniaturization of CMOS devices […]
