Micromagnetic Simulation Results for Fe-Ni Alloys Across 3-300 nm Grain Sizes

High-resolution micromagnetic simulation results for metallic iron and iron-nickel alloys at room temperature. The dataset systematically explores grain sizes from 3 to 300 nm and axial ratios from 1 to 5, authored by Yuqin Wang and last updated on 2026-04-25. It includes files for magnetic domain states, hysteresis parameters, and relaxation-time data derived from Nudged Elastic Band calculations.

Use Cases

• Modeling magnetic domain state transitions based on grain size and axial ratio parameters mentioned in the description
• Analyzing hysteresis behavior (Bc, Mrs/Ms) for kamacite, taenite, and tetrataenite alloys
• Estimating magnetic relaxation times for nanoscale particles using Nudged Elastic Band calculation results
• Verifying simulation data consistency through mesh partitioning analysis described in the dataset

Strengths

• Systematically explores two key parameters: grain size (3-300 nm) and axial ratio (1-5).
• Includes results for four specific material types: α-Fe, kamacite, taenite, and tetrataenite.
• Data is provided in multiple structured Excel files covering domain states, hysteresis, and relaxation times.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small in scale at 201.1 KB, indicating a limited scope of simulation runs.
