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…
Spin Peltier effect and its length scale in Pt/YIG system at high temperatures
Atsushi Takahagi, Takamasa Hirai, Ryo Iguchi +3
The temperature and yttrium-iron-garnet (YIG) thickness dependences of the spin Peltier effect (SPE) have been investigated using a Pt/YIG junction system at temperatures ranging f…
Seebeck-driven transverse thermoelectric generation in on-chip devices
Weinan Zhou, Takamasa Hirai, Ken-ichi Uchida +1
An unconventional approach to enhance the transverse thermopower by combining magnetic and thermoelectric materials, namely the Seebeck-driven transverse thermoelectric generation…
Sm-Co-based amorphous alloy films for zero-field operation of transverse thermoelectric generation
Rajkumar Modak, Yuya Sakuraba, Takamasa Hirai +8
Transverse thermoelectric generation using magnetic materials is essential to develop active thermal engineering technologies, for which the improvements of not only the thermoelec…
Deposition temperature dependence of thermo-spin and magneto-thermoelectric conversion in CoMnGa films on YFeO and GdGaO
Hayato Mizuno, Rajkumar Modak, Takamasa Hirai +4
We have characterized CoMnGa (CMG) Heusler alloy films grown on YFeO (YIG) and GdGaO (GGG) substrates at different deposition temperatures and inv…
