摘要
Coercivities of 1400 kA/m (17.6 kOe) and 650 kA/m (8.2 kOe) were achieved in mechanically milled and spark plasma sintered Fe35Pt35P30 and Fe50Pt50 bulk magnets, respectively. The constituent phases were analysed by X-ray diffraction and transmission electron microscopy and the effect of microstructure on magnetic properties is discussed. (C) 2004 Acta Materialia Inc.
