Antiferromagnetic structure in tetragonal CuMnAs thin films (2015)
Journal Article
Wadley, P., Hills, V. A., Shahedkhah, M. R., Edmonds, K. W., Campion, R. P., Novák, V., …Jungwirth, T. (2015). Antiferromagnetic structure in tetragonal CuMnAs thin films. Scientific Reports, 5(1), Article 17079. https://doi.org/10.1038/srep17079

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...

Magnetic coupling in ferromagnetic semiconductor (Ga,Mn)As/(Al,Ga,Mn)As bilayers (2015)
Journal Article
Wang, M., Wadley, P., Campion, R. P., Rushforth, A. W., Edmonds, K. W., Gallagher, B. L., …Langridge, S. (2015). Magnetic coupling in ferromagnetic semiconductor (Ga,Mn)As/(Al,Ga,Mn)As bilayers. Journal of Applied Physics, 118(5), Article 053913. https://doi.org/10.1063/1.4928206

We report on a study of ferromagnetic semiconductor (Ga,Mn)As/(Al,Ga,Mn)As bilayers using magnetometry and polarized neutron reflectivity (PNR). From depth-resolved characterization of the magnetic structure obtained by PNR, we concluded that the (Ga...

Resonant driving of magnetization precession in a ferromagnetic layer by coherent monochromatic phonons (2015)
Journal Article
Jäger, J., Scherbakov, A., Glavin, B., Salasyuk, A., Campion, R., Rushforth, A., …Bayer, M. (2015). 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
Akimov, A., Poyser, C. L., Kent, A. J., & CAMPION, R. (2015). Coherent phonon optics in a chip with an electrically controlled active device. Scientific Reports, 5, https://doi.org/10.1038/srep08279

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.
