Critical Behaviour in the Spin Fluctuations and Superfluid Density of La${}_{2-x}$Sr${}_x$CuO${}_4$

C. Panagopoulos, B. D. Rainford, J. R. Cooper +2

We study the doping dependence of low frequency spin fluctuations and the zero-temperature superfluid density of La${}_{2-x}$Sr${}_x$CuO${}_4$ using the muon spin relaxation ($\mu$SR) and…
