Abstract
Magnetization induced optical second harmonic generation is used to investi gate the surface magnetic properties during the layer-by-layer growth of Co films on Cu(001). The second harmonic (SH) signal changes as a function of Co thickness and an oscillatory behavior of the SH asymmetry with one mono layer period is observed for the transverse Kerr-geometry and s-polarized i ncident light, while the average SH signal has no such oscillations. The ma gnetization induced SH signal at half filled layers is enhanced with respec t to that of filled layers, which agrees with the enhancement of magnetic m oment of edge atoms and the higher step density at half filled layers. Its dependences on the growth rate and temperature are discussed. (C) 1999 Amer ican Institute of Physics. [S0021-8979(99)40508-0].
