Pressure induced magnetic order in FeSe

Abstract

The magnetic order induced by the pressure was studied in single crystalline FeSe by means of muon-spin rotation ($\mu$SR) technique. By following the evolution of the oscillatory part of the $\mu$SR 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 45${}^{\mathrm{o}}$. The value of the magnetic moment per Fe atom was estimated to be $\simeq 0.13-0.14$~${\mu }_{\mathrm{B}}$ at $p\simeq 1.9$~GPa.
