## Description

- description: " Wepropose and demonstrate a quantitative noncontact measurement method
    for the thermal Hall effect (THE) based on magnetic-field-modulated lock-in thermography
    (LIT). This method enables visualization of THE-induced temperature change and
    quantitative estimation of the thermal Hall angle θTHE by applying periodic magnetic
    fields to a sample and obtaining the first-harmonic response of thermal images.
    By combining this method with LIT-based measurement techniques for the longitudinal
    thermal conductivity κxx, we also quantify the transverse thermal conductivity
    κxy. We validate our measurement methods by estimating θTHE, κxx,and κxy in a
    ferromagnetic Heusler alloy Co2MnGa slab showing large THE."
