High-resolution neutron spectroscopy and neutron diffraction results on the magnetic properties of Tb in the high-Tc superconductor are presented. The lowest-lying crystalline-electric-field transition, expected at , is not observed, indicating that the system can still be described in the mean-field approximation at 20 K, well above TN (4 K). The inelastic neutron spectra can be decomposed into an elastic and a quasi-elastic part, indicating that a single Lorentzian does not describe well the magnetic-response function and/or that Tb 2D short-range correlations persist up to temperatures above 100 K.
