Abstract

The datasets presented in this article are related to materials research on hard ferromagnet in TM-Fe-Si (TM=Ti, Zr, Hf, V, Nb, and Ta) ternary systems. The motivation for data collection is based on the research paper entitled "Novel hard magnetic phase with Zr_11.5Fe₅₃Si_35.5 composition". The datasets are composed of scanning electron microscope images, X-ray diffraction (XRD) patterns, and magnetization data for TM₇Fe₅₂Si₄₁ annealed at 1050 °C. The chemical compositions of constituent phases were determined by an energy dispersive X-ray spectrometer (EDS). The phase analysis was performed using XRD and EDS results. The Curie temperature of each sample was obtained using magnetization data, and the coercive field was determined for hard ferromagnet samples Zr₇Fe₅₂Si₄₁ and Hf₇Fe₅₂Si₄₁. The datasets would be useful for developing an Fe-based rare-earth-free permanent magnet, which is one of the central issues of materials science.
