Composition-tunable magnon-polaron anomalies in spin Seebeck effects in epitaxial BiYFeO films
Takashi Kikkawa, Koichi Oyanagi, Tomosato Hioki +5
We have investigated hybridized magnon-phonon excitation (magnon polarons) in spin Seebeck effects (SSEs) in BiYFeO (BiYIG; , , and $…
Triplon current generation in solids
Yao Chen, Masahiro Sato, Yifei Tang +6
A triplon refers to a fictitious particle that carries angular momentum corresponding to the elementary excitation in a broad class of quantum dimerized spin systems. Such…
Observation of nuclear-spin Seebeck effect
T. Kikkawa, D. Reitz, H. Ito +10
Thermoelectric effects have been applied to power generators and temperature sensors that convert waste heat into electricity. The effects, however, have been limited to electrons…
Magnon polarons in the spin Peltier effect
Reimei Yahiro, Takashi Kikkawa, Rafael Ramos +4
We report the observation of anomalous peak structures induced by hybridized magnon-phonon excitation (magnon polarons) in the magnetic field dependence of the spin Peltier effect…
Absence of evidence of spin transport through amorphous YFeO
Juan M. Gomez-Perez, Koichi Oyanagi, Reimei Yahiro +4
Long-distance transport of spin information in insulators without long-range magnetic order has been recently reported. Here, we perform a complete characterization of amorphous Y$…
Magnetic field dependence of the nonlocal spin Seebeck effect in Pt/YIG/Pt systems at low temperatures
Koichi Oyanagi, Takashi Kikkawa, Eiji Saitoh
We report the nonlocal spin Seebeck effect (nlSSE) in a lateral configuration of Pt/YFeO(YIG)/Pt systems as a function of the magnetic field (up to 10 T) at vari…
