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…
Direct imaging of current-induced antiferromagnetic switching revealing a pure thermomagnetoelastic switching mechanism
H. Meer, F. Schreiber, C. Schmitt +6
We unravel the origin of current-induced magnetic switching of insulating antiferromagnet/heavy metal systems. We utilize concurrent transport and magneto-optical measurements to i…
Identification of Néel vector orientation in antiferromagnetic domains switched by currents in NiO/Pt thin films
Christin Schmitt, Lorenzo Baldrati, Luis Sanchez-Tejerina +14
Understanding the electrical manipulation of antiferromagnetic order is a crucial aspect to enable the design of antiferromagnetic devices working at THz frequency. Focusing on col…
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…
