Amorphous Fe-Ti-Sb (FTS) thin film was prepared on a 0.3-µm SiO2/Si wafer by a DC magnetron sputtering method to investigate the spintronic thermoelectric (STE) properties based on the anomalous Nernst effect (ANE) and spin Seebeck effect (SSE). A platinum (Pt) ultra-thin layer was coated on top FTS (Pt/FTS) thin film surface to be used for the spin Hall detector. The crystal structure, morphology, composition and magnetic characteristics of as-deposited FTS and Pt/FTS thin films were carried out by x-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDS), and vibrating sample magnetometry (VSM), respectively. As a result, the crystal structure and morphology displayed a metallic-glass type within the amorphous phase and a smooth surface. The magnetic characterization showed that an ANE and SSE of FTS thin film to yield a spin Seebeck coefficient (Ss) of around 0.35 µV K− 1.
