Highly Efficient Experimental System for Thermomagnetic Coefficient Calculations

The thermomagnetic coefficients play a pivotal role in converting heat to electricity in ferromagnetic systems. Specifically, the Anomalous Nernst Effect and Longitudinal Spin-Seebeck Effect show promise for energy conversion. However, traditionally, calculating thermomagnetic coefficients relies on a limited value of thermal gradient measurements due to experimental constraints. In this study, we introduce a novel experimental setup aimed at generating thermomagnetic curves with a significantly higher density of data points, enhancing the reliability of coefficient calculations. Our proposed setup enables the attainment of
$\Delta$
T values of up to 40 K without the thermal annealing on the films, due to the highly efficient thermal dissipation.
