Abstract

The field of spin caloritronics, which explores the interplay between spin current and thermal effects, is a promising path for new energy-efficient-electronic devices. However, current thermoelectric technologies are limited by conventional material choices and device designs. Antiferromagnetic materials, with their unique spin structure and magnetic characteristics, provide new opportunities for enhanced thermoelectric performance through spin-dependent effects. This review covers origin and measurement methodologies of anomalous Nernst effect, focusing on non-collinear antiferromagnets. By presenting insights into the relationship between electronic structure and thermoelectric performance as well as their practical measurements, this review aims to pave the way for developing AFM-based thermoelectric devices in advanced energy technologies. © 2024
