      abstract     = {We excited an epitaxial magnetic Ag/Fe/Cr/Fe multilayer
                      nonthermally and nonoptically with very short (<1 ps)
                      electromagnetic pulses. We detected the synchronous
                      phononic-magnetic response by time-resolved magneto-optical
                      Kerr effect measurements. The Ag/Fe/Cr/Fe multilayer was
                      patterned into a coplanar waveguide transmission line, and
                      the electromagnetic pulses were generated by pulsed-laser
                      illumination of an integrated GaAs photoconductive switch
                      (PCS). The detected magnetic excitations comprise up to four
                      narrow-band high-order modes with the highest frequency
                      reaching 30 GHz. The mode frequencies are independent of
                      both temperature in the range from 16 to 300 K and the
                      applied external magnetic field up to 120 mT. Our analysis
                      shows that the origin of the rigidity of these
                      high-frequency modes is the strong coupling of the magnetic
                      subsystem with the lattice of the Ag/Fe/Cr/Fe multilayer.
                      The exciting electromagnetic pulse generated by the PCS
                      induces, via magnetoelastic coupling, long-lived (ns)
                      standing GHz acoustic waves normal to the Ag/Fe/Cr/Fe film
                      plane. These lattice oscillations in turn couple back and
                      drive the magnetization oscillations via the magnetoelastic
                      coupling. The temperature and field dependence of the
                      damping of the oscillations can be described by inelastic
                      phonon-phonon and phonon-magnon scattering. Our study opens
                      up a possibility of using coherent lattice and magnetization
                      dynamics in ferromagnetic films for spintronic devices at
                      GHz clock rates.},
