Effect of substrate and geometry on the size of the anomalous Nernst phenomenon
Golub, Dmitrii ; Zázvorka,, Jakub (oponent) ; Čech, Vladimír (vedoucí práce)
The anomalous Nernst effect refers to the transverse voltage generated in magnetic materials to applied longitudinal temperature gradient. The effect holds promise for applications in spin caloritronics and enhanced thermoelectric energy conversion. Here, we investigate the influence of the sample substrate and experimental geometry on the anomalous Nernst effect in sputtered permalloy thin film samples. We investigated the anomalous Nernst effect on samples with four different substrates of substantially different thermal conductivities. Moreover, four distinct techniques of generating thermal gradient in our samples were tested: three methods for generating in-plane gradients and one method for the out-of-plane gradient generation. We observe that the substrate thermal conductivity significantly affects the magnitude of the temperature gradient. Consistent anomalous Nernst effect coefficient is measured in two in-plane configurations, out-of-plane temperature gradient was estimated based on the acquired data.
