“…Generation, manipulation, and detection of spin polarization by ultrafast laser pulses are powerful techniques in the field of spintronics and magnetism [1][2][3][4][5]. Such operations rely on laser pulse-induced demagnetization due to heating [6], the change of magnetic anisotropy due to charge transfer [1,2], magnetooptical (inverse) Faraday effect (IFE) [7][8][9], and (inverse) the Cotton-Mouton effect [10]. Recent experiments demonstrated magnetoelastic coupling of coherent acoustic sound waves generated by the local heating caused by optical gratings [11,12] and laser spots [13][14][15][16] with spin waves.…”
