Nonreciprocity reversal of magnetoacoustic attenuation in NiFe alloy thin films
Mingran Xu, Kei Yamamoto, Kouta Kondou +8
Nonreciprocity, the asymmetry of transport, underlies technologies from the diode to the microwave isolator. In a ferromagnet, a surface acoustic wave generates an elliptical effec…
Magnon-polaron control in a surface magnetoacoustic wave resonator
Kevin Künstle, Yannik Kunz, Tarek Moussa +6
Strong coupling between distinct quasiparticles in condensed matter systems gives rise to hybrid states with emergent properties. We demonstrate the hybridization of confined phono…
Controlling spin currents with magnon interference in a canted antiferromagnet
Lutong Sheng, Anna Duvakina, Hanchen Wang +16
Controlling spin current lies at the heart of spintronics and its applications. The sign of spin currents is monotonous in ferromagnets once the current direction is determined. Sp…
Spin current generation by acousto-electric evanescent wave
Takuya Kawada, Masashi Kawaguchi, Kei Yamamoto +5
We experimentally demonstrate that a spin current can be induced by the acousto-electric evanescent wave, an electric field associated with surface acoustic waves (SAWs) that decay…
Electromagnetic evanescent field associated with surface acoustic wave: Response of metallic thin films
Takuya Kawada, Kei Yamamoto, Masashi Kawaguchi +5
Surface acoustic waves (SAWs), coherent vibrational modes localized at solid surfaces, have been employed to manipulate and detect electronic and magnetic states in condensed-matte…
Observation of nonreciprocal diffraction of surface acoustic wave
Yoichi Nii, Kei Yamamoto, Masaki Kanno +2
Rectification phenomenon caused by the simultaneous breaking of time reversal and spatial inversion symmetries has been extended to a wide range of (quasi)particles and waves; howe…
Valley-Selective Phonon-Magnon Scattering in Magnetoelastic Superlattices
Liyang Liao, Jorge Puebla, Kei Yamamoto +5
Phonons and magnons are engineered by periodic potential landscapes in phononic and magnonic crystals, and their combined studies may enable valley phonon transport tunable by the…
Acoustically driven magnon-phonon coupling in a layered antiferromagnet
Thomas P. Lyons, Jorge Puebla, Kei Yamamoto +5
Harnessing the causal relationships between mechanical and magnetic properties of van der Waals materials presents a wealth of untapped opportunity for scientific and technological…
