Stress tensor mesostructures for freeform shaping of thin substrates

Kavli Affiliate: Youwei Yao | First 5 Authors: Youwei Yao, Brandon Chalifoux, Ralf Heilmann, Mark Schattenburg, | Summary: Stress-induced shaping, which deforms thin substrates utilizing stressed surface coatings, has enabled and enhanced a host of applications in past decades. Owing to the touchless fabrication process compatible with modern planar technology, the method has been applied […]

Directional excitation of a high-density magnon gas using coherently driven spin waves

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Brecht G. Simon, Samer Kurdi, Helena La, Iacopo Bertelli, Joris J. Carmiggelt | Summary: Controlling magnon densities in magnetic materials enables driving spin transport in magnonic devices. We demonstrate the creation of large, out-of-equilibrium magnon densities in a thin-film magnetic insulator via microwave excitation of […]
