説明:

Transverse thermoelectric generators (TTEGs) based on the anomalous Nernst effect can operate without the need for an external magnetic field by incorporating permanent magnets. Utilizing permanent magnets with a large anomalous Nernst coefficient is needed to enhance power density, thereby improving the efficiency of electricity generation from waste heat. Several commercially available permanent magnets have been considered for demonstration of the zero magnetic field operation of TTEGs, including SmCo5, Sm2Co17, and Nd2Fe14B-based magnets. However, there are limited studies on transverse thermoelectric properties of the bulk permanent magnets without the use of rare earth element as potential candidates for the TTEGs. In this work, we have systematically studied the evolution of the magnetic and transverse thermoelectric properties of isotropic MnAlGe-based permanent magnets upon Cr substitution for Mn.
