Time-resolved magnetization-induced second-harmonic generation from the Ni„110... surface

Relaxation processes on the picosecond and subpicosecond time scale after optical excitation have been studied by time-resolved magnetization-induced second-harmonic generation from ferromagnetic nickel. A fast drop of the second-harmonic intensity and the Kerr-signal within 300 fs after optical excitation has been observed which is followed by a partial recovery within a few picoseconds. We sh...

Vector Angle of Remanent Magnetization

-A simple method for estimating the remanent magnetization vector angle (e) is introduced. By using this method, the orientation effects of Ba-ferrite FDs on the effective vector angle for the remanent magnetization and on recording characteristics were investigated. The resul ts show that the angle e depends on perpendicular squareness ratio (S~) and is independent from Hc. Also, the larger th...

Magnetization-induced second-harmonic generation of light by exchange-coupled magnetic layers

A longitudinal magneto-optical Kerr effect and magnetization-induced second-harmonic generation (MSHG) of light (at 2v) have been measured in a SiO2/Fe96Si4/Dy30Fe58Co12/glass exchange-coupled magnetic bilayer system with competitive anisotropies. Theoretical MSHG predictions in this structure that give rise to an effect proportional to magnetization components and that are allowed by an electr...
