Abstract
The influence of surface magnetization of polycrystalline nickel samples on Second-Harmonic Generation (SHG) in reflection was investigated using pleosecond laser pulses of 600 nm. The effect was measured for different polarization combinations with samples under normal conditions. For the azimuthal rotation of the magnetization anisotropies of (13±2)% and (19±3)% were observed for s→P and p→P polarization, respectively. The Kerr angle observed by. SHG was found to be an order of magnitude larger (4±1)o than the linear Kerr angle. A hysteresis curve was recorded for p→P polarization. No influence of the oxide layer was noticed.
