Atypical vortex lattice and the magnetic penetration depth in superconducting Sr${}_2$RuO${}_4$ deduced by $\mu$SR

M. Yakovlev, Z. Kartsonas, J. E. Sonier

The muon spin rotation ($\mu$SR) technique has been applied to determine the behavior of the in-plane magnetic penetration depth (${\lambda }_{ab}$) in the vortex state of the unconventional…
