- W1993965362 abstract "Phase relations in second-harmonic generation (SHG) have been studied systematically for Ni and Co films on Cu(001) as a function of thickness in the range 1--12 ML. Below two monolayers we observe, with s-polarized fundamental light and P-polarized second-harmonic light, phase shifts close to 180ifmmode^circelsetextdegreefi{} of both films against the Cu substrate. Such large phase shifts in this polarization combination appear to be characteristic of the transition from s- to d-band metals. In the ferromagnetic thickness range the relative phase between odd and even tensor elements becomes important. For Ni films it is independent of film thickness for both $stackrel{ensuremath{rightarrow}}{p}P$ and $stackrel{ensuremath{rightarrow}}{s}P$ polarizations, and leads to the ratio ${ensuremath{chi}}_{mathrm{xyy}}^{mathrm{odd}}/{ensuremath{chi}}_{mathrm{zyy}}^{mathrm{even}}=0.047ifmmodepmelsetextpmfi{}0.013,$ in agreement with theoretical predictions. In the case of Co films the relative phase differs dramatically between these two polarization combinations. It is nearly independent of film thickness for $stackrel{ensuremath{rightarrow}}{p}P$ polarized SHG. However, for $stackrel{ensuremath{rightarrow}}{s}P$ polarization it varies from 135ifmmode^circelsetextdegreefi{} at 3 ML to 60ifmmode^circelsetextdegreefi{} at 10 ML, causing a sign change of the magnetic contrast at 90ifmmode^circelsetextdegreefi{} near 6 ML. The ratio of odd to even second-harmonic field amplitudes was found to vary from 22% at 3 ML to 12.5% above 6 ML. From these results we conclude that measurements of the relative phase are necessary for deriving reliable information from SHG about the magnetization state of a sample." @default.
