Visualizing Vortex Cluster Dynamics in the Weak Type-II Superconductor CaSb
Yusuke Iguchi, Nabhanila Nandi, Mohamed Oudah
Scanning SQUID imaging of CaSb reveals dense vortex clusters with enhanced boundary susceptibility and suppressed internal vortex motion, which features inconsistent with both…

Magnetic edge fields in UTe near zero background fields
Yusuke Iguchi, Huiyuan Man, S. M. Thomas +5
Chiral superconductors are theorized to exhibit spontaneous edge currents. Here, we found magnetic fields at the edges of UTe, a candidate odd-parity chiral superconductor, tha…
