Giant oscillatory Gilbert damping in superconductor-ferromagnet-superconductor junctions

Interfaces between materials with differently ordered phases present unique opportunities for exotic physical properties, especially the interplay between ferromagnetism and superconductivity in the ferromagnet/superconductor heterostructures. The …

Nematicity Arising from a Chiral Superconducting Ground State in Magic-Angle Twisted Bilayer Graphene under In-Plane Magnetic Fields

Recent measurements of the resistivity in magic-angle twisted bilayer graphene near the superconducting transition temperature show two-fold anisotropy or nematicity when changing the direction of an in-plane magnetic field [Cao \textit{et al.}, …

Spin-Wave Doppler Shift by Magnon Drag in Magnetic Insulators

Doppler shift, magnetic insulators, spin-wave instability, magnon-magnon interactions.

Optical manipulation of domains in chiral topological superconductors

Optical control of chirality in chiral superconductors bears potential for future topological quantum computing applications. When a chiral domain is written and erased by a laser spot, the Majorana modes around the domain can be manipulated on …

Indirect Interactions between Magnets in The 2021 Magnonics Roadmap (Perspective Article),

Magnonics is a rather young physics research field in nanomagnetism and nanoscience that addresses the use of spin waves (magnons) to transmit, store, and process information. After several papers and review articles published in the last decade, …

Nonreciprocal coherent coupling of nanomagnets by exchange spin waves (cover paper)

Nanomagnets are widely used to store information in non-volatile spintronic devices. Spin waves can transfer information with low-power consumption as their propagations are independent of charge transport. However, to dynamically couple two distant …

Magnetic resonance imaging of spin-wave transport and interference in a magnetic insulator

Spin waves—the elementary excitations of magnetic materials—are prime candidate signal carriers for low-dissipation information processing. Being able to image coherent spin-wave transport is crucial for developing interference-based spin-wave …

Nonreciprocal surface magnetoelastic dynamics

Motivated by recent experiments, we investigate the nonreciprocal magnetoelastic interaction between the surface acoustic phonons of dielectric nonmagnetic substrates and magnons of proximity nanomagnets. The magnetization dynamics exerts rotating …

Non-reciprocal pumping of surface acoustic waves by spin wave resonances (Editors' Suggestion)

We predict that surface acoustic waves are generated preferentially in one direction in a heterostructure of a thin magnetic film on a non-magnetic substrate. The non-reciprocity arises from magneto-elastic coupling and magneto-rotation coupling, the …

Magnon trap by chiral spin pumping (Editors' Suggestion)

Chiral spin pumping is the generation of a unidirectional spin current in half of ferromagnetic films or conductors by dynamic dipolar stray fields from close-by nanomagnets. We formulate a general theory of long-range chiral interactions between …
