Perpendicular switching of a single ferromagnetic layer induced by in-plane current injection
Ioan Mihai Miron,Kevin Garello,Gilles Gaudin,Pierre-Jean Zermatten,Marius V. Costache,Stéphane Auffret,S. Bandiera,Bernard Rodmacq,Alain Schuhl,Pietro Gambardella +9 more
TL;DR: To prove the potential of in-plane current switching for spintronic applications, this work constructs a reprogrammable magnetic switch that can be integrated into non-volatile memory and logic architectures.

Perpendicular switching of a single ferromagnetic layer induced by in-plane current injection
Kevin Garello,Ioan Mihai Miron,Gilles Gaudin,Pierre-Jean Zermatten,Marius V. Costache,Stéphane Auffret,Sebastien Bandera,B. Rodmacq,Alain Schuhl,Pietro Gambardella +9 more
TL;DR: In this article, the authors demonstrate switching of a perpendicularly magnetized cobalt dot driven by in-plane current injection at room temperature, which is composed of a thin cobalt layer with strong perpendicular magnetic anisotropy and Rashba interaction induced by asymmetric platinum and AlOx interface layers.
Journal ArticleDOI
Current-driven spin torque induced by the Rashba effect in a ferromagnetic metal layer
Ioan Mihai Miron,Gilles Gaudin,Stéphane Auffret,Bernard Rodmacq,Alain Schuhl,Stefania Pizzini,Jan Vogel,Pietro Gambardella,Pietro Gambardella +8 more
TL;DR: It is demonstrated that strong magnetic fields can be induced in ferromagnetic metal films lacking structure inversion symmetry through the Rashba effect and this process makes it a realistic candidate for room-temperature spintronic applications.
Journal ArticleDOI
Symmetry and magnitude of spin-orbit torques in ferromagnetic heterostructures
Kevin Garello,Ioan Mihai Miron,Can Onur Avci,Frank Freimuth,Yuriy Mokrousov,Stefan Blügel,Stéphane Auffret,Olivier Boulle,Gilles Gaudin,Pietro Gambardella,Pietro Gambardella +10 more
TL;DR: This work reports on the three-dimensional vector measurement of SOTs in AlOx/Co/Pt and MgO/CoFeB/Ta trilayers using harmonic analysis of the anomalous and planar Hall effects and demonstrates that heavy metal/ferromagnetic layers allow for two different Sots having odd and even behaviour with respect to magnetization reversal.
Journal ArticleDOI
Giant Magnetic Anisotropy of Single Cobalt Atoms and Nanoparticles
Pietro Gambardella,Stefano Rusponi,M. Veronese,Sarnjeet S. Dhesi,C. Grazioli,A. Dallmeyer,Iván Cabria,Rudolf Zeller,Peter H. Dederichs,Klaus Kern,Carlo Carbone,Harald Brune +11 more
TL;DR: The isotropic magnetic moment of a free atom is shown to develop giant magnetic anisotropy energy due to symmetry reduction at an atomically ordered surface and the results confirm theoretical predictions and are of fundamental value to understanding how magnetic an isotropy develops in finite-sized magnetic particles.
