  1. Negative/positive signs indicate distinct averaged moment directions projected in the \(\hat{z}\)-axis. The minus sign denotes an antiparallel spin orientation. (P) denotes theoretical results considering no imperfections at the interfaces (pristine) and (I-R) for calculations considering both interdiffusion and roughness at interfaces (see Supplementary Note 3 for details). Here, the uncertainty for the experimental results is 0.05 μB  ⋅ atom−1.
  2. aNote that \({\bar{\mu }}_{s}\to 0\) due to the almost antiferromagnetic spin configuration throughout the Gd thickness. However, absolute values amount to  ~7.6 μB  ⋅ atom−1 (see Fig. 5a).
