6. 1w comparison – on the pad vs. off the pad

7. Observations Output DC intensity and 1ω signal show clear reductions on the pad. However, 2ω signal is barely changed (it has increased noise on the pad). Coercivity shows no change. These results are consistent with ferromagnetic coupling of the two layers. Still need to explain why the 1ω shows a larger change than the 2ω. A total of 10 pads were looked at on this sample. All showed similar behavior.
