The crystal and magnetic structures of the perovskite YBaCuFeO5+δ have been studied in the temperature range T = 4.2-300 K by powder neutron diffraction. In addition to the antiferromagnetic ordering transition at TN = 442 K, a commensurate-incommensurate magnetic transition is detected at T′N = 190 K. Below this temperature, two sets of satellite peaks surround the (1/2, 1/2, 1/2) magnetic peak at d ∼ 5.15 Å, collapsing into a single set of satellites below 155 K. Polarization analysis has been performed to confirm the magnetic nature of the (1/2, 1/2, 1/2)± satellites.
