中文摘要Bulk Nd-Al-Fe-Co glassy alloys with diameter up to 5 mm were investigated by magnetic measurements, magnetic force microscopy (MFM) and high resolution electron microscopy (HREM) at room temperature. The results from the measurement of vibrating sample magnetometer show that these samples with compositions Nd65Al10Fe25-xCox, (x = 0-10 at.%) and Nd60Al10- Fe20Co10 display hard magnetic properties with H-C of similar to300 kAm(-1), Ms of similar to 10 Am-2 kg(-1), and M-r of similar to 7 Am-2 kg(-1). The MFM measurements of the Nd60Al10Fe20Co10 bulk metallic glass (BMG) reveal the existence of magnetic domains with a period of about 0.36 mum, and the ordered clusters with the averaged size of about 5 nm was observed by the HREM on the sample. The domain structure or cluster is believed to be associated with the appearance of hard-magnetic properties in this alloy system. The existence of the large-size domains demonstrates that magnetic moment of a great deal of ordered atomic clusters in the BMG has been aligned by exchange-coupling. (C) 2002 Elsevier Rience Ltd.
