Abstract
We report for the first time experiments showing a magnetic-field-induced e nhancement of second-harmonic generation (SHG) on the Si(111)-7 x 7 surface . An externally applied magnetic field of 10 T increased the SHG intensity of a selected susceptibility tensor element by approximate to 100% at room temperature and by approximate to 500% at 120 K. The observed SHG enhanceme nt is induced by the magnetization of the Si(111)-7 x 7 surface. The electr on spins on the dangling bonds are suggested to be responsible for the magn etization.
