Neutron polarization analysis was carried out for Bragg lines at ( 1 3, 1 3, ℓ) and ( 2 3, 2 3, ℓ) of an ErFe2O4 single crystal at 15 K. Magnetic part of the intensity was analyzed as a sum of three sinusoidal curves. Correlation length of spins along the c axis is only up to about 8 Å or 1 3 of the unit cell.
