“…We have proposed the concept of optical signal delay and optical buffer memory on the basis of non-equilibrium state of magnetization caused by the pulsed, optical excitation [1][2][3] . Preferred device structures which suit for those applications would be a hybrid structure consisting of an optical waveguide and a magnetic thin layer with sufficient magneto-optical (MO) coupling between the two constituent components.…”

Dependence of photo-induced FMR (phi-FMR) on incident angle of excitation and probing laser beams has been studied in a [Co (dCo = 0.78 nm) / Pd (dPd = 0.81 nm) ]5 multi-layer film with the aim to find experimentally the limitation of inducement and detection of magnetization dynamics with oblique light incidence. We have found, in the experiments changing the incident angle of a pump beam, that phi-FMR is observed up to the grazing incident angle of 88 with p-polarized excitation pulses, whereas it disappears at the incidence angle of around 65 with s-polarized excitation. As for the experiments changing the incident angle of a probe beam, phi-FMR disappears at the incidence angle of 65 for both s-and p-polarizations, whereas it reappears with further increasing the angle for the p-polarization and vanishes at 75 .
