It has been found that, instead of the expected critical acceleration of the longitudinal spin relaxation near the Néel temperature in stoichiometric LaMnO3 samples, the relaxation is sharply retarded. This slowing down is similar to that observed earlier in doped manganites with ferromagnetic ordering.
