Gradual emergence of superconductivity in underdoped LSCO

Ana-Elena Tutueanu, Machteld E. Kamminga, Tim B. Tejsner +13

We present triple-axis neutron scattering studies of low-energy magnetic fluctuations in strongly underdoped La${}_{2-x}$Sr${}_x$CuO${}_4$ with $x=0.05$, $0.06$ and $0.07$, providing…
