The exchange constant in units of J/m is a bulk property. There are only two possibilities (1) Either there is a phase that separates the Nd2Fe14B and Fe. This intermediate phase will have a certain thickness. In addition to the exchange constant the authors should give the thickness of the intermediate phase. (2) There is a coupling between the different phases. This is normally expressed as a surface energy. The proper units will be J/(m*m).ÎÒ¿´µ½ºÜ¶àÎÄÏ×ÖÐËùÓõ½µÄÈíÓ²´Å²ãÖ®¼äµÄ½»»»³£ÊýµÄµ¥Î»¶¼ÊÇJ/m£¬¿ÉÊÇÉó¸åÈËÌáµ½µÄÕâ¸öintermediate phase µÄºñ¶ÈÓÖÔõôµÃÖªÄØ£¿»¹ÊDz»ÐèÒª¿¼ÂÇÂð£¿Çó¸÷λţÈ˰ï°ïÎÒ£¬·Ç³£¸Ðл£¡ |
