| Zusammenfassung | In ultra-low field nuclear magnetic resonance (ULF-NMR) with strong prepolarization field (Bp), type-II superconducting pick-up coils may be vulnerable to flux pinning from the strong Bp Pick-up coils made of NbTi, Nb, and Pb were evaluated in terms of acquired NMR signal quality. The type-II pick-up coils showed degraded signals above 61 mT maximum exposure, while the Pb pick-up coil exhibited no such degradation. Furthermore, a negative counter pulse following a strong Bp was shown to follow magnetic hysteresis loop to unpin the trapped flux in the type-II pick-up coil and restore the NMR signal. |
