Hot off the Press!! Back-to-back publications in JACS by the collaborative effort of Han, Ramanathan, Shimon, Takahashi, Equbal at 3.4 and 7 Tesla, and by Kaminker group at 14 Tesla!
Check our most recent publication on P1 center diamonds titled " P1 Center Electron Spin Clusters Are Prevalent in Type 1b Diamonds." Complimented with Ilia Kaminker's most recent paper published in JACS titled "Nitrogen Substituents Aggregation and Clustering in Diamonds as Revealed by High-Field Electron Paramagnetic Resonance." These papers feature the surprising discovery in two back-to-back studies that a large fraction of nitrogen (P1) defects in type 1b diamond, commonly used for ensemble quantum sensing, form exchange-coupled clusters (indicated as 6 connected blue spheres).
