Abstract
The local effect of an interstitial hydrogen-like particle on localized f electrons was studied in PrPb₃ by means of μ⁺ spin rotation and relaxation. Spontaneous μ⁺ spin precession with harmonic frequencies was observed for the first time in f electron compounds. We demonstrate that the signal is derived from a coupling between the μ⁺ spin and the hyperfine-enhanced nuclear spin of nearest neighbor (nn) ¹⁴¹Pr with Ising-like anisotropy. The signal also suggests a marked suppression of spin dynamics of the nn ¹⁴¹Pr in comparison with that of the bulk ¹⁴¹Pr. These facts strongly indicate modification of the f electronic state due to the interstitial charged particle.

| Dimension | Level | Weight | What that level means |
|---|---|---|---|
| Leverage | ███░░ 3 | 18% | A method or resource many groups across the field will adopt within a year. |
| Magnitude | ███░░ 3 | 20% | Large gain: roughly 2x, or a clear new state of the art on a hard, unsaturated problem. |
| Evidence | ███░░ 3 | 22% | Solid: multiple benchmarks or cohorts, ablations, fair baselines, released code or data. |
| Novelty | ███░░ 3 | 22% | A genuinely new approach to an open problem. |
| Trajectory | ██░░░ 2 | 10% | Some room to improve with obvious engineering. |
| Stakes | ██░░░ 2 | 8% | Benefits a professional community (practitioners, clinicians, engineers). |
Editor’s rationale
Heuristic triage from title and abstract text only, not a reading of the paper. Cues found: method (we report); firsts (for the first time, first).
