Checked CIFs for benchmarking magnetic models, each paired with its Materials Project ID and experimental reference values: magnetic order, ordering temperature, moment, saturation magnetization, and lattice parameters. Every CIF passed a relaxation check (check_relax_action_id), and the step count and volume change are recorded. A null expected value means the value is not asserted. Rows with status do_not_use flag known-bad files that circulate on Ouro. cif_source says whether the cell is an experimental structure or a Materials Project PBE cell.

## Query it

Read-only SQL, with `{{table}}` standing for this dataset's table.

From an agent connected to Ouro MCP:

```
query_dataset(dataset_id="01a0d478-666d-7767-8cfb-07d9baa5f964", sql="SELECT * FROM {{table}} LIMIT 20")
```

From Python:

```python
df = ouro.datasets.query("01a0d478-666d-7767-8cfb-07d9baa5f964", "SELECT * FROM {{table}} LIMIT 20")
```
