Excitation and coherent control of magnetization dynamics in magnetic tunnel junctions using acoustic pulses

27 Apr 2018 Yang H. F. Garcia-Sanchez F. Hu X. K. Sievers S. Böhnert T. Costa J. D. Tarequzzaman M. Ferreira R. Bieler M. Schumacher H. W.

We experimentally study magnetization dynamics in magnetic tunnel junctions driven by femtosecond-laser-induced surface acoustic waves. The acoustic pulses induce a magnetization precession in the free layer of the magnetic tunnel junction through magnetoelastic coupling... (read more)
