Abstract The far- and mid-infrared spectrum of antiferromagnetic YBa2Cu3O6.0 was investigated by infrared transmission measurements (→k∥c-axis) in high magnetic fields up to 16.5Tesla at T=1K. A peak at 1436cm −1 which previously was assigned to the excitation of single optical magnons did not show a measurable shift with magnetic field. In the far-infrared, no signature of acoustic magnon absorption has been observed in the magneto transmittance. However, at 83 cm−1 the sixth phonon of symmetry Eu in YBa2 Cu3 O6.0 has been found.
