Textured heterogeneity in square artificial spin ice
J. C. T Lee, S. K. Mishra, V. S. Bhat +8
We report evidence of spontaneous formation of a heterogeneous network of superdomains in two-dimensional square artificial spin ice nanostructures in externally applied magnetic f…

Magnetically Charged Superdomain Walls In Square Artificial Spin Ice
J. C. T Lee, S. K. Mishra, V. S. Bhat +8
We report direct evidence that magnetically charged superdomain walls form spontaneously in two dimensional square artificial spin ice nanostructures in response to external magnet…

Synthesizing Skyrmion Molecules in Fe-Gd Thin Films
J. C. T Lee, J. J. Chess, S. A. Montoya +9
We show that properly engineered amorphous Fe-Gd alloy thin films with perpendicular magnetic anisotropy exhibit room-temperature skyrmion molecules, or a pair of like-polarity, op…
