The authors report low-temperature magnetic relaxation measurements of nanometre-scale antiferromagnetic horse-spleen ferritin particles. It is argued that the magnetic relaxation signal is due to the excess uncompensated spins. Their key observation is the non-thermal character of the relaxation below 2 K. The observed features are in agreement with theoretical suggestions on quantum tunnelling of the Neel vector between easy directions.
