Session questions:
  1. Why there is no uniformity in the 200 nm disk?
  2. Do you relate the change of damping to the change of H_eff (because both could be due to a modification of the BiYIG properties due to patterning)?
  3. Could you share a bit more information about how to grow such a low-damping Bi-doped YIG film since it is very difficult?

We kindly ask the speakers to reply to any questions left unanswered during the talk.

1- indeed, due to its smaller size, the uniformity of magnetic parameters (Ku) is much better in the 200 nm nanodisk than in the larger disks.
2- yes, we believe that these two effects are intimately related.
3- Please check DOI: 10.1038/s41467-018-05732-1 and Lucile Soumah's thesis, which you'll find online.
