Dispersion and energy spectrum of spin excitations in an underdoped La_1.90Sr_0.10CuO_4

M. Kofu, T. Yokoo, F. Trouw +1

We performed inelastic neutron experiments on underdoped La_2-xSr_xCuO_4(x=0.10, T_c=28.6K) using a time-of-flight neutron scattering technique. Four incommensurate peaks on the tw…
