Temperature dependences of structure and coercivity for melt-spun MnBi compound

► MnBi compound was investigated by neutron/X-ray powder diffraction and magnetic measurements. ► c/a lattice parameter ratio of the MnBi increases with the increasing temperature. ► No structural phase transition is observed for nanoscale MnBi at 633 K. ► Temperature dependence of the coercivity is studied.
