We study the structural and magnetic properties of the MnBi inter-metalliccompound. The LTP (Low Temperature Phase) MnBi compound is successfullysynthesized in single step by vacuum encapsulation technique and rapidquenching from phase formation temperature. The phase purity and the magneticmoments of MnBi are highly dependent on heat treating schedule. The best phasepurity and the magnetic moment are found for a sample heat treated at 310oC for48h. Rietveld fitted X-ray diffraction (XRD) patterns revealed that the studiedMnBi compound is crystallized in hexagonal P63/mmc space group with minutepresence of unreacted Bi and Mn phases. The scanning electron microscopy (SEM)study is carried out to visualize the grains morphology and phaseidentification. The bulk MnBi powder showed appreciable magnetic moment of(62emu/g at 6Tesla) and maximum energy product (BHmax of 4.01MGOe at 6Tesla).The magnetic properties of synthesized MnBi show that it could be a potentialcandidate for rare earth free permanent magnets.
