## Description

- description: We propose a simple and reliable measurement method for the thermal
    Hall effect by the use of thermocouples fabricated directly on a target material.
    The thermal Hall angle has been typically characterized by measuring diagonal
    and off diagonal terms of the thermal conductivity tensor with manually attached
    bulk thermometers such as thermocouples and resistance temperature sensors. However,
    the presence of contact thermal resistance between the material and thermometers
    and the ambiguity of actual temperature information under a magnetic field hinder
    the quantitative evaluation of the thermal Hall angle. In this work, to characterize
    the temperature gradient with low contact thermal resistance, we deposit a thermoelectric
    NiCu thin film directly on the target materials, pattern it into a crossbar shape,
    and attach two Au wires at the hot and cold junctions to form a closed electrical
    circuit, i.e., an on-slab thermocouple. Owing to the ideal fourfold symmetry of
    the structure, we can determine the thermal Hall angle simply from the ratio of
    the measured thermoelectric voltages in the longitudinal (input) and transverse
    (output) directions for the on-slab thermocouples under the out-of-plane magnetic
    field. The measurements for the Co2MnGa Heusler alloy and Ni slabs by the proposed
    method find that the thermal Hall effect was clearly detected in a wide temperature
    range from 60 to 330 K, which is quantitatively consistent with the literature.
    This approach offers a simple and reliable route to investigate the thermal Hall
    effect and reveal the wide variety of carrier transport and thermal conversion
    phenomena.
