The magnetic order induced by the pressure was studied in single crystalline FeSe by means of muon-spin rotation (μSR) technique. By following the evolution of the oscillatory part of the μSR signal as a function of angle between the initial muon-spin polarization and 101 axis of studied crystal it was found that the pressure induced magnetic order in FeSe corresponds either to the collinear (single-stripe) antiferromagnetic order as observed in parent compounds of various FeAs-based superconductors or to the Bi-Collinear order as obtained in FeTe system, but with the Fe spins turned by 45o. The value of the magnetic moment per Fe atom was estimated to be ≃0.13−0.14~μB at p≃1.9~GPa.
