How this map works
Official field. Every mineral node is on the final USGS 2025 Critical Minerals List.
Position. DOE application rows influence location. Position is connection, not ranking.
Review depth. Evidence review is separate from official designation and application use.
Material systems. Related material systems remain a separate layer rather than being relabeled as official critical minerals.
Rare-earth convention. The Atlas 15-count follows the controlled USGS commodity grouping used here; scandium remains separately listed.
Evidence boundary. Supported facts stay supported. Unknowns stay visible.
Public method. M0 identifies the experimental public evidence method used here. It does not indicate readiness, qualification, certification, or acquisition approval.

MATERIAL IDENTITY
Y₃Fe₅O₁₂
Engineered magnetic material system. Reviewed public context.
- What it is
- YIG is an engineered magnetic material used in magnonics and related microwave and spin research.
- Why it matters
- YIG shows why an engineered material system cannot be understood from critical-mineral designation alone. Substrate choice, material growth, fabrication, and validation remain distinct parts of the pathway.

Critical-Mineral Dependencies Across Common YIG Stacks
Yttrium is the YIG critical-mineral constituent. Gadolinium gallium garnet (GGG) and yttrium scandium gallium aluminum garnet (YSGAG) introduce additional critical-mineral dependencies in common or emerging substrate systems.

- 01Supported evidenceCritical Materials
Yttrium is the critical-mineral anchor for YIG. Common YIG substrate systems introduce additional critical-mineral dependencies through GGG or YSGAG.
- 02First unresolved linkQualified Material Stack
Public evidence reviewed here does not establish qualified precursor form, purity, processor, substrate lot, repeatability, or assured supply for a mission-relevant YIG stack.
Evidence basis: No qualifying public evidence was identified in the reviewed corpus for a BN7-specific precursor form, purity, processor, substrate lot, repeatability, or assured mission-relevant YIG material stack.
- 03Later-stage contextThin-Film / Crystal Growth
Peer-reviewed work demonstrates low-damping YIG thin films, including liquid-phase epitaxy and high-quality YIG on garnet substrates.
- 04Later-stage contextDevice Fabrication
Peer-reviewed device work demonstrates YIG-on-GGG resonators and microfabrication approaches; this establishes feasibility context, not a qualified production line.
- 05Later-stage contextRoom-Temperature Research
A 2024 peer-reviewed experiment implemented quantum logic on a room-temperature hybrid magnon-spin system using a YIG film and NV centers. This is a research demonstration, not proof of scalable room-temperature quantum computing.
- 06Unresolved questionTesting & Validation
Mission-relevant proof would require independent acceptable ranges for damping/linewidth, propagation loss, temperature and field behavior, substrate effects, repeatability, yield, interfaces, and device-level performance.
Evidence basis: The reviewed literature identifies relevant material and substrate performance variables, but it does not provide a mission-specific acceptance range, independent qualification protocol, repeatability baseline, or production-yield criterion.

No program-specific qualified supplier path, acquisition route, transition sponsor, demand commitment, or acceptance baseline is established by this public snapshot.
