Pyroelectricity of magnetite along the triclinic a, b and c axes was measured over the temperature range from 4.2 K to 20 K. It was found that the pyroelectricity along the triclinic a axis begins to decrease at 6 K, as the temperature is increased, while the one along the b and c axes begins to increase at the same temperature.
