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,…
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…
GHz sample excitation at the ALBA-PEEM
Muhammad Waqas Khaliq, José M. Álvarez, Antonio Camps +9
We describe a setup that is used for high-frequency electrical sample excitation in a cathode lens electron microscope with the sample stage at high voltage as used in many synchro…
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…
