A comparison between rare earth and transition metals working as magnetic materials in an AMR refrigerator in the room temperature range

- Comparison between different magnetic materials.
- 2D model of an Active Magnetic Regenerative refrigeration cycle.
- Validation of the model with experimental data.
- Gd5(SixGe1−x)4 is the most performant magnetic material.
- The most promising are LaFeSi compounds which are cheaper and they give high performances.
