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 $…
Mechanism of paramagnetic spin Seebeck effect
Koichi Oyanagi, Saburo Takahashi, Takashi Kikkawa +1
We have theoretically investigated the spin Seebeck effect (SSE) in a normal metal (NM)/paramagnetic insulator (PI) bilayer system. Through a linear response approach, we calculate…
Deciphering quantum fingerprints in electric conductance
Shunsuke Daimon, Kakeru Tsunekawa, Shinji Kawakami +5
When the electric conductance of a nano-sized metal is measured at low temperatures, it often exhibits complex but reproducible patterns as a function of external magnetic fields,…
Anomalous Ettingshausen effect in iron-carbon alloys
Ren Nagasawa, Koichi Oyanagi, Takamasa Hirai +3
We have investigated the anomalous Ettingshausen effect (AEE) in iron-carbon alloys, i.e., cast irons and steel, using the lock-in thermography. All the alloys exhibit the clear AE…
