Using spatial light interference of ultrafast laser pulses, we generate a lateral modulation in the magnetization profile of an otherwise uniformly magnetized film, whose magnetic excitation spectrum is monitored via the coherent and resonant interac

Publikováno v: Phys. Rev. B 95, 060409 (2017)

We demonstrate the nonlinear frequency conversion of ferromagnetic resonance (FMR) frequency by optically excited elastic waves in a thin metallic film on dielectric substrates. Time-resolved probing of the magnetization directly witnesses magneto-el

Ultrafast Magnetoelastic Probing of Surface Acoustic Transients

Autor: Janušonis, J., Chang, C. L., Jansma, T., Gatilova, A., Lomonosov, A. M., Shalagatskyi, V., Vlasov, V. S., Temnov, V. V., Tobey, R. I.

We generate in-plane magnetoelastic waves in nickel films using the all-optical transient grating technique. When performed on amorphous glass substrates, two dominant magnetoelastic excitations can be resonantly driven by the underlying elastic dist
