Popis: Zero field spontaneous magnetization curves have been determined by nuclear magnetic resonance technique. Fitting these curves on numerical calculations on a renormalized spin wave model yields values of the anisotropy in the exchange interaction ranging from 4×10 -3 to 10 -2 . These values are compared with those obtained form small field susceptibility experiments at low temperature.
