In doped La2-xSrxCuO4, magnetic spin fluctuations are described by a damped harmonic oscillator, with damping largest near (0.2,0.2) and susceptibility growing toward the antiferromagnetic wavevector (1/2,1/2).
S(Q,ω ) is, in turn, proportional to χ′′(Q,ω ) multiplied by the Bose factor n(ω) + 1 = [1− exp(−¯hω/kBT )]−1

Anisotropic damping of the spin fluctuations in doped La2-xSrxCuO4 studied by resonant inelastic x-ray scattering
In doped La2-xSrxCuO4, magnetic spin fluctuations are described by a damped harmonic oscillator, with damping largest near (0.2,0.2) and susceptibility growing toward the antiferromagnetic wavevector (1/2,1/2).
