Effect of magnetic anisotropy relaxation on laser-induced magnetization precession in thin galfenol films (2021)
Journal Article
Gerevenkov, P. I., Kuntu, D. V., Filatov, I. A., Shelukhin, L. A., Wang, M., Pattnaik, D. P., Rushforth, A. W., Kalashnikova, A. M., & Khokhlov, N. E. (2021). Effect of magnetic anisotropy relaxation on laser-induced magnetization precession in thin galfenol films. Physical Review Materials, 5(9), Article 094407. https://doi.org/10.1103/PhysRevMaterials.5.094407

The rate and pathways of relaxation of a magnetic medium to its equilibrium following excitation with intense and short laser pulses are the key ingredients of ultrafast optical control of spins. Here we study experimentally the evolution of the magn... Read More about Effect of magnetic anisotropy relaxation on laser-induced magnetization precession in thin galfenol films.

Protected Long-Distance Guiding of Hypersound Underneath a Nanocorrugated Surface (2021)
Journal Article
Yaremkevich, D. D., Scherbakov, A. V., Kukhtaruk, S. M., Linnik, T. L., Khokhlov, N. E., Godejohann, F., Dyatlova, O. A., Nadzeyka, A., Pattnaik, D. P., Wang, M., Roy, S., Campion, R. P., Rushforth, A. W., Gusev, V. E., Akimov, A. V., & Bayer, M. (2021). Protected Long-Distance Guiding of Hypersound Underneath a Nanocorrugated Surface. ACS Nano, 15(3), 4802–4810. https://doi.org/10.1021/acsnano.0c09475

In nanoscale communications, high-frequency surface acoustic waves are becoming effective data carriers and encoders. On-chip communications require acoustic wave propagation along nanocorrugated surfaces which strongly scatter traditional Rayleigh w...

Magnetism and magnetoresistance in the critical region of a dilute ferromagnet (2021)
Journal Article
Wang, M., Howells, B., Marshall, R. A., Taylor, J. M., Edmonds, K. W., Rushforth, A. W., Campion, R. P., & Gallagher, B. L. (2021). Magnetism and magnetoresistance in the critical region of a dilute ferromagnet. Scientific Reports, 11, Article 2300. https://doi.org/10.1038/s41598-021-81893-2

We present detailed experimental measurements and simulations of the field-dependent magnetization and magnetoresistance in the vicinity of the Curie temperature in the highly disordered dilute ferromagnetic semiconductor (Ga,Mn)As. The observed depe... Read More about Magnetism and magnetoresistance in the critical region of a dilute ferromagnet.
