Tetragonal CuMnAs is an antiferromagnetic material with favourable properties for applications in spintronics. Using a combination of neutron diffraction and x-ray magnetic linear dichroism, we determine the spin axis and magnetic structure in tetrag...

Resonant driving of magnetization precession in a ferromagnetic layer by coherent monochromatic phonons (2015)
Journal Article

Resonant driving of magnetization precession in a ferromagnetic layer by coherent monochromatic phonons. Physical review B: Condensed matter and materials physics, 92(2), https://doi.org/10.1103/PhysRevB.92.020404

We realize resonant driving of the magnetization precession by monochromatic phonons in a thin ferromagnetic layer embedded into a phononic Fabry-Pérot resonator. A femtosecond laser pulse excites resonant phonon modes of the structure in the 10−40 G...

Coherent phonon optics in a chip with an electrically controlled active device (2015)
Journal Article

Phonon optics concerns operations with high-frequency acoustic waves in solid media in a similar way to how traditional optics operates with the light beams (i.e. photons). Phonon optics experiments with coherent terahertz and sub-terahertz phonons p... Read More about Coherent phonon optics in a chip with an electrically controlled active device.
