Direct measurement of electrocaloric effect based on multi-harmonic lock-in thermography
Ryo Iguchi, Daisuke Fukuda, Jun Kano +2
In this study, we report on a direct measurement method for the electrocaloric effect, the heating/cooling upon application/removal of an electric field in dielectric materials, ba…
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…
Excitations of the ferroelectric order
Ping Tang, Ryo Iguchi, Ken-ichi Uchida +1
We identify the bosonic excitations in ferroelectrics that carry electric dipoles from the phenomenological Landau-Ginzburg-Devonshire theory. The "ferron" quasi-particles emerge f…
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…
Temperature profile of the Thomson-effect-induced heat release/absorption in junctionless single conductors
Takahiro Chiba, Ryo Iguchi, Takashi Komine +2
The Thomson effect induces heat release or absorption under the simultaneous application of a charge current and a temperature gradient to conductors. Here, we theoretically invest…
