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…
