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.}, …

Imaging spin-wave damping underneath metals using electron spins in diamond

Spin waves in magnetic insulators are low-damping signal carriers that could enable a new generation of spintronic devices. The excitation, control, and detection of spin waves by metal electrodes is crucial for interfacing these devices to …

Chiral Excitations in Spintronics (long review article)

We recently witnessed the discovery of various chiral interactions between magnetic, phononic, electronic, and photonic excitations in spintronics that mediate the excitation of quasiparticles into a single direction, leading to phenomena such as …

Chiral Coupling to Magnetodipolar Radiation (comprehensive review chapter)

We review and extend the theory of chiral pumping of spin waves by magnetodipolar stray fields that generate unidirectional spin currents and asymmetric magnon densities. We illustrate the physical principles by two kinds of chiral excitations of …

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 …
