Dataset Name

FeAl-mMTP-Verification

Description

Verification set for magnetic Moment Tensor Potentials (mMTPs) for the bcc Fe-Al system. Contains 336 configurations of 16-atom Fe-Al supercells with collinear atomic magnetic moments, used to validate mMTPs trained on the companion training set (FeAl-mMTP-Train). Configurations generated using constrained DFT (cDFT) with ABINIT and PAW PBE pseudopotentials with a 6x6x6 k-point mesh and 25 Hartree plane-wave cutoff energy. mMTPs predict formation energy, lattice parameters, and total magnetic moments of bcc Fe-Al at 0 K.Note: ColabFit dataset contains energy, atomic forces, and stress. Refer to the original files for per-atom magnetic moment data.

Usage

ds.parquet : Aggregated dataset information.
co/ directory: Configuration rows each include a structure, calculated properties, and metadata.
cs/ directory : Configuration sets are subsets of configurations grouped by some common characteristic. If cs/ does not exist, no configurations sets have been defined for this dataset.
cs_co_map/ directory : The mapping of configurations to configuration sets (if defined).
