Twist-Tuned Magnonic Nanocavity Mode in a Trilayer Moiré Superlattice
Tianyu Yang, Gianluca Gubbiotti, Marco Madami +2
The concept of moiré superlattices has recently been introduced into the field of magnonics, enabling unprecedented control over spin-wave propagation and confinement in nanoscale…
Curvilinear magnonic crystal based on 3D hierarchical nanotemplates
Gianluca Gubbiotti, Olha Bezsmertna, Oleksandr V. Pylypovskyi +11
Curvilinear magnetic nanostructures enable control of magnetization dynamics through geometry-induced anisotropy and chiral interactions as well as magnetic field modulation. In th…
Atomic-scale Origin of Interfacial Dzyaloshinskii--Moriya Interaction in Pt/Fe/Au
Emanuele Longo, Gianluca Gubbiotti, Matteo Belli +4
Recent results show remarkable interfacial--Dzyaloshinskii--Moriya interaction (i-DMI) in magnetic heterostructures composed of relatively thick Fe thin films ( nm). To inve…
Magnon-Magnon Interaction Induced by Dynamic Coupling in a Hybrid Magnonic Crystal
