摘要：
The effects of contents of Fe and B and microstructure on the intergrain interactions in the nanocomposite Pr2Fe14 B/alpha -Fe permanent magnetic materials are investigated by measuring the deltaM-H curves. The intergrain interactions become stronger with the increase in the content of Fe. The larger deltaM value of the ribbon samples corresponds to the smaller grain size and uniform grain size distribution, which are favorable factors strengthening the intergrain interactions and exchange-coupling. The non-ferromagnetic phase Pr1.1Fe4B4 is found in grain boundaries when the content of B is larger, which weakens the intergrain interactions.
