Key points
- It produced Fe-Se-H powder by thermally diffusing hydrogen at 180 degrees and 5 atmospheres into FeSe single crystals with a critical temperature of 8K for 10 hours.
- Using EPR spectroscopy, it measured magnetic-field-dependent microwave absorption up to 6000Oe at 3.6–25K and 295K.
- It interpreted U-shaped nonlinear absorption and quasiperiodic signals as evidence of a type-II superconductor's mixed state and Abrikosov vortices.
- Based on these signals, the authors claim that superconductivity exists even at 295K under normal pressure, suggesting the possibility of room-temperature superconductivity.
- However, the work relies on interpretation of EPR signals rather than direct transition measurements of electrical resistance or magnetization, so independent reproduction and cross-validation are essential.
