摘要：
An enhancement of the coercivity, H-C, has been observed in SmCo5 when ball-milled with antiferromagnetic NiO powders. Moreoever. after short-term milling, these composites exhibit very high values of the squareness without need for particle alignment. Classical AM plots show that short-range exchange interactions are predominant for fields H<H-C, while long-range magnetostatic interactions prevail for H>H-C. (C) 2002 Elsevier Science B.V.
