As in YBa2Cu3O6+x and HgBa2CuO8+∞, the pseudogap state in Bi2Sr2CaCu2O8+∞ is characterized by the existence of an intra-unit-cell magnetic order revealed by polarized neutron scattering technique. We report here a supplementary set of polarized neutron scattering measurements for which the direction of the magnetic moment is determined and the magnetic intensity is calibrated in absolute units. These data allow a close comparison between bilayer systems YBa2Cu3O6+x and Bi2Sr2CaCu2O8+∞ and raise important questions concerning the range of the magnetic correlations and the role of disorder around optimal doping.
