Preliminary studies in June revealed candidate peaks. However, degradation of the sample limited our ability to reproduce the results. We would like to continue this research, using the L_III edge rather than L_II, and taking precautions to reduce sample damage. We will cool the sample in the Displex (if available) or keep it in a He atmosphere (if it is not). We anticipate that reduction of third-harmonic intensity by means of the mirrors will make a major improvement in the sample degradation problem. All necessary components for the experiment will be ready by mid September. equipment+required: Displex, UIUC Polarimeter experiment: Induced magnetic order in GMR multilayers hazards: None name: Myron B.
