Observation of nonlocal ferron-drag thermoelectricity
Takuma Itoh, Takamasa Hirai, Ping Tang +8
The Peltier effect induces a heat current when a charge current passes through a conductor. Since a charge current is conserved at the junction between two different conductors, th…
Thermoelectric response of a ferroelectric insulator
Ryo Iguchi, Takashi Teranishi, Sakyo Hirose +4
Thermoelectric effects enable the conversion between heat and electricity without moving parts. While conventionally associated with mobile charges, we report thermoelectricity cau…
Quantitative noncontact measurement of thermal Hall angle and transverse thermal conductivity by lock-in thermography
Takumi Imamura, Takamasa Hirai, Koichi Oyanagi +4
We propose and demonstrate a quantitative noncontact measurement method for the thermal Hall effect (THE) based on magnetic-field-modulated lock-in thermography. This method enable…
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…
