中文摘要	Pr8Fe88B4 ribbons prepared by melt spinning have been investigated by x-ray diffraction, differential thermal analysis, thermomagnetic analysis, atom force microscopy, and superconducting quantum interface device magnetometer. The results show that the annealed ribbons consist of the Pr2Fe14B and alpha -Fe phases. The magnetization of soft alpha -Fe phase remains parallel to the magnetization of the hard Pr2Fe14B phase for fields less than the exchange field (H-ex). The exchange field in exchange-spring magnets, determined from the demagnetization curves measured at various temperatures, increases with decreasing grain size and measure temperature. The temperature dependence of exchange field was analyzed qualitatively by the expression H-ex = (AK)(1/2)/(M(s)t). (C) 2001 American Institute of Physics.
