Zusammenfassung:•Isotropic MnBi nanoparticles were prepared by reactive sintering of Mn nanoparticles and Bi.•Anisotropic bulk MnBi was prepared by reactive sintering under a magnetic field of 5 T.•Magnetic fields enhance the formation of MnBi and orient the c-axis of MnBi along the fields. The isotropic nanoparticles (NPs) and anisotropic bulk samples of MnBi were prepared from Mn NPs by using zero-field and field-assisted reactive sintering, respectively. The MnBi NPs are irregular in shape with size d
