Evolution of spin excitations in superconducting La${}_{2-x}$Ca${}_x$CuO${}_{4-\hat{I}´}$ from the underdoped to the heavily overdoped regime

S. Hameed, Y. Liu, M. Knauft +8

We investigate high-energy spin excitations in hole-doped La${}_{2-x}$Ca${}_x$CuO${}_{4-\hat{I}´}$ films across a broad Ca doping range $x=0.05-0.50$ using resonant inelastic x-ray scatter…
