Two-Component Anomalous Hall and Nernst Effects in Anisotropic Fe_{4<b>-</b> <i>x</i>} Ge _<i>x</i> N Thin Films.

ABSTRACT: A series of thin films Fe_4-x Ge _x N (x = 0 - 1) were fabricated onto MgO substrates by magnetron sputtering with the aim of studying the possible enhancement of the anomalous Nernst effect (ANE), envisaged based on density functional theory (DFT) calculations. The Nernst and Hall effects of the series were systematically analyzed, complemented with resistivity, magnetic, electron microscopy, and Mössbauer experiments, and DFT calculations including elastic properties. The Fe₄N phase crystallizes in the cubic symmetry with Pm3̅m space group, whereas a small tetragonal distortion is realized in Fe_4-x Ge _x N films for x > 0.35. From the comparison of the experimental isomer shift wit
