It has been shown that the magnetic field increases the energy gap and can even induce it at temperatures higher than T-p2 by 15-20 K. As the field strength increases, the peak amplitude of the gap singularity of the tunneling spectrum first increases, reaches its maximum at 20-30 T, and then decreases. The increase in the gap peak amplitude is attributed to the field-induced improvement of the condition of the CDW nesting, while the decrease in the amplitude in high fields, to the breakdown of the ground state caused by its Zeeman splitting.","pubDate":"2026-10-20","url":"https://hal.science/hal-00997887"},"indexado":"2026-10-20T12:23:04.288Z"}}
