Chiral-phonon generation of orbital currents in light transition metals
Marc Rovirola, Júlia Òdena, Anna Castellví +10
Orbital angular momentum offers a new channel for information transport in a vast set of materials. Its coherent generation and detection remain, however, largely unexplored. Here,…
Hierarchical domain structures in buckled ferroelectric free sheets
David Pesquera, Kumara Cordero-Edwards, Marti Checa +11
Flat elastic sheets tend to display wrinkles and folds. From pieces of clothing down to two-dimensional crystals, these corrugations appear in response to strain generated by sheet…
Magnetoacoustic waves in a highly magnetostrictive FeGa thin film
Marc Rovirola, M. Waqas Khaliq, Blai Casals +11
The interaction between surface acoustic waves and magnetization offers an efficient route for electrically controlling magnetic states. Here, we demonstrate the excitation of magn…
Study of the magnetoelastic effect in nickel and cobalt thin films at GHz range using X-ray microscopy
Marc Rovirola, Muhammad Waqas Khaliq, Travis Gustafson +9
We use surface acoustic waves of 1 and 3 GHz in hybrid piezoelectric-magnetic systems with either cobalt or nickel as a magnetic layer to generate magnetoacoustic waves and directl…
Magneto-Acoustic Waves in antiferromagnetic CuMnAs excited by Surface Acoustic Waves
M. Waqas Khaliq, Oliver Amin, Alberto Hernández-Mínguez +15
Magnetoelastic effects in antiferromagnetic CuMnAs are investigated by applying dynamic strain in the 0.01% range through surface acoustic waves in the GaAs substrate. The magnetic…
Resonant and off-resonant magnetoacoustic waves in epitaxial FeSi/GaAs hybrid structures
Marc Rovirola, M. Waqas Khaliq, Blai Casals +6
Surface acoustic waves (SAWs) provide an efficient dynamical coupling between strain and magnetization in micro/nano-metric devices. Using a hybrid device composed of a piezoelectr…
Giant topological Hall effect in correlated oxide thin films
Lorenzo Vistoli, Wenbo Wang, Anke Sander +15
Strong electronic correlations can produce remarkable phenomena such as metal-insulator transitions and greatly enhance superconductivity, thermoelectricity, or optical non-lineari…
Generation and imaging of magnetoacoustic waves over millimetre distances
Blai Casals, Nahuel Statuto, Michael Foerster +7
Using hybrid piezoelectric/magnetic systems we have generated large amplitude magnetization waves mediated by magneto-elasticity with up to 25 degrees variation in the magnetizatio…
Giant Optical Polarization Rotation Induced by Spin-Orbit Coupling in Polarons
Blai Casals, Rafael Cichelero, Pablo García Fernández +7
We have uncovered a giant gyrotropic magneto-optical response for doped ferromagnetic manganite La2/3Ca1/3MnO3 around the near room-temperature paramagnetic-to-ferromagnetic transi…
