FeGe Phases: Raman Spectroscopy and Magnetic Properties Data

Experimental and computational data from a 2021 CrystEngComm manuscript by Anna Kúkoľová of École Polytechnique Fédérale de Lausanne. The data establishes reference Raman signatures for distinguishing between cubic, hexagonal, and tetragonal phases in the FeGe system. The results are substantiated by first-principles lattice dynamics calculations, transmission electron microscopy, X-ray diffraction, and magnetic measurements.

Use Cases

• Training phase classification models based on reference Raman signatures described in the manuscript.
• Validating first-principles lattice dynamics calculations against experimental Raman and magnetic data.
• Developing materials fabrication methods by distinguishing between FeGe hexagonal and cubic structures.
• Benchmarking structural characterization techniques like TEM and XRD using the provided experimental results.

Strengths

• Data is associated with a peer-reviewed publication in CrystEngComm (2021).
• Experimental results are supported by multiple complementary characterization methods: first-principles calculations, TEM, XRD, and magnetic measurements.
• The dataset establishes reference Raman signatures for multiple FeGe phases (FeGe, FeGe2, Fe2Ge3).

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
