Magnetic excitations of the charge stripe electrons below half doping in La2-xSrxNiO4 (x = 0.45, 0.4)

The low energy magnetic excitation spectrum of charge stripe ordered La2-xSrxNiO4, x=0.4 and x=0.45 samples, were studied by neutron scattering. Two excitation modes are observed in both materials, one from the ordered magnetic moments, and a second mode consistent with pseudo-one-dimensional antife...
