【Abstract】 MnBi phase has remarkable ferromagnetism and magneto-optical effect, and permanent-magnetic and magneto-optical materials can be fabricated by the use of Bi-Mn alloys. The dope in Bi-Mn alloys can improve their performance. Some new Bi-Mn compounds have shown attractive characteristics such as colossal magetoresistance and ferroelectric effects. The solidification microstructure and properties of Bi-Mn alloys are affected by applied electric or magnetic field. Several recent research progresses are reviewed.更多还原
