Depth-dependent study of time-reversal symmetry-breaking in the kagome superconductor $A$V${}_3$Sb${}_5$

J. N. Graham, C. Mielke, D. Das +21

The breaking of time-reversal symmetry (TRS) in the normal state of kagome superconductors $A$V${}_3$Sb${}_5$ stands out as a significant feature. Yet the extent to which this effe…
