Current-driven asymmetric magnetization switching in perpendicularly magnetized CoFeB/MgO heterostructures


Reference: J. Torrejon et al., Phys. Rev. B 91, 214434 (2015). By using analytical theory and micromagnetics simulations, we helped to explain experimental observations of an asymmetry in current-induced magnetization switching in ultrathin CoFeB/MgO films.

Narrow Magnonic Waveguides Based on Domain Walls


Reference: F. Garcia-Sanchez et al., Phys. Rev. Lett. 114, 247206 (2015). By using spin wave theory and micromagnetics simulations, we have shown that localized eigenmodes of magnetic domain walls can act as efficient waveguides for spin waves in ultrathin films. This work has just appeared in Physical Review Letters. Last modified 23/06/15

Synchronization of stochastic oscillators


Reference: N. Locatelli et al., “Noise-Enhanced Synchronization of Stochastic Magnetic Oscillators”, Physical Review Applied 2, 034009 (2014). Our recent study on the noise-induced synchronization of stochastic magnetic oscillators, based on magnetic tunnel junctions in the superparamagnetic state, has just appeared in Physical Review Applied.
