Line Plot from Scientific Research

The cwEPR signal of PNRs in the solid state measured over a wide magnetic field range (at room temperature) shows both the unpaired electron peak at 320 mT sitting atop a much larger FMR signal at 82 mT, suggesting an internal field of 240 mT (green curve; 15, low field signal: internal field aligned to the magnetic field). The sample (a PNR film made in the inner wall of an EPR tube; Supplementary Notes 9 and 15 ) is highly inhomogeneous, hence rotation results in a shift in the resonance positions (red curve; 105, high field signal: internal field anti-aligned to the magnetic field).
