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 $…
Indirect optical manipulation of the antiferromagnetic order of insulating NiO by ultrafast interfacial energy transfer
Stephan Wust, Christopher Seibel, Hendrik Meer +14
We report the ultrafast, (sub)picosecond reduction of the antiferromagnetic order of the insulating NiO thin film in a Pt/NiO bilayer. This reduction of the antiferromagnetic order…
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…
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…
Spin Seebeck effect in the layered ferromagnetic insulators CrSiTe and CrGeTe
Naohiro Ito, Takashi Kikkawa, Joseph Barker +3
We have studied the longitudinal spin Seebeck effect (LSSE) in the layered ferromagnetic insulators CrSiTe and CrGeTe covered by Pt films in the measurement configuration w…
