Unveiling two-dimensional electron systems on ultra-wide bandgap semiconductor -GaO

Ryu Yukawa, Hiroshi Mizuseki, Suryo Santoso Putro +26

Ultra-wide bandgap (UWBG) semiconductors promise to revolutionize power electronics, yet a fundamental understanding of their interfacial electronic structure has been hindered by…

Optimizing the magnon-phonon cooperativity in planar geometries

K. An, C. Kim, K. -W. Moon +7

Optimizing the cooperativity between two distinct particles is an important feature of quantum information processing. Of particular interest is the coupling between spin and phono…

Non-local magnon transconductance in extended magnetic insulating films.\\ Part I: spin diode effect

Ryuhei Kohno, Kyongmo An, Eric Clot +14

This review provides a comprehensive study of the nonlinear transport properties of magnons, which are electrically emitted or absorbed inside extended YIG films by spin transfer e…

Bright and dark states of two distant macrospins strongly coupled by phonons

Kyongmo An, Ryuhei Kohno, Artem N. Litvinenko +10

We study the collective dynamics of two distant magnets coherently coupled by acoustic phonons that are transmitted through an intercalated crystal. By tuning the ferromagnetic res…

Enhancement of YIGPt spin conductance by local Joule annealing

Ryuhei Kohno, Nicolas Thiery, Kyongmo An +7

We report that Joule heating can be used to enhance the interfacial spin conductivity between a metal and an oxide. We observe that local annealing of the interface at about 550\,K…

Short-range Thermal Magnon Diffusion in Magnetic Garnet

Kyongmo An, Ryuhei Kohno, Nicolas Thiery +8

Using the spin Seebeck effect (SSE), we study the propagation distance of thermal spin currents inside a magnetic insulator thin film in the short-range regime. We disambiguate spi…

Domain wall propagation by spin-orbit torques in in-plane magnetized systems

Ryuhei Kohno, João Sampaio, Stanislas Rohart +1

The effect of damping-like spin-orbit torque (DL SOT) on magnetic domain walls (DWs) in in-plane magnetised soft tracks is studied analytically and with micromagnetic simulations.…

Coherent long-range transfer of angular momentum between magnon Kittel modes by phonons

Kyongmo An, Artem N. Litvinenko, Ryuhei Kohno +13

We report ferromagnetic resonance in the normal configuration of an electrically insulating magnetic bilayer consisting of two yttrium iron garnet (YIG) films epitaxially grown on…
