## Description

- description: Heat-to-charge conversion efficiency of thermoelectric materials is
    closely linked to the entropy per charge carrier. Thus, magnetic materials are
    promising building blocks for highly efficient energy harvesters, as their carrier
    entropy is boosted by a spin degree of freedom. In this work, we investigate how
    this spin-entropy impacts heat-to-charge conversion in A-type antiferromagnet
    CrSBr. We perform simultaneous measurements of electrical conductance and thermocurrent
    while changing magnetic order using temperature and magnetic field as tuning parameters.
    We find a strong enhancement of the thermoelectric power factor around the Néel
    temperature. We further reveal that the power factor at low temperature can be
    increased by up to 600% upon applying a magnetic field. Our results demonstrate
    that the thermoelectric properties of 2D magnets can be optimized by exploiting
    the sizeable impact of spin-entropy and confirm thermoelectric measurements as
    a sensitive tool to investigate subtle magnetic phase transitions in low-dimensional
    magnets.
