Abstract

Fine particles of MnBi were prepared by the hydrogen plasma metal reaction method and their magnetic properties were investigated. The particle size of the as-prepared MnBi particles was 70950nm with a median diameter of 269 nm. Heat treatment and ball milling with a dispersant improved the magnetic properties of the particles. The sample annealed at 330°C for 5 h in Ar then ball-milled for 10 min with a dispersant showed the largest energy product of 105 kJ̇m-3 and a saturation magnetization of 71.0Am 2̇kg-1. High coercivity of 1380 kȦm-1 was also obtained for the sample that was ball-milled for 2 h.
