| 中文摘要 | In a real magnet, the relation between isothermal remanence J(r)(H) and dc demagnetization remanence J(d)(H) is expressed as deltam(H) =[J(d)(H) -J(r)(infinity) +2J(r)(H)]/ J(infinity). It is believed that nonzero deltam is due to the interactions between particles in the magnet. Using Pr2Fe14B as a sample, the relation is examined by the micromagnetic finite element method. The positive value of deltam is primarily caused by intergrain exchange coupling. The decrease of intergrain exchange coupling results in the drop of the maximum value of deltam. However, the variation of anisotropy in grain boundaries produces no change in the maximum value of deltam. A Henkel plot is suggested to be effective for checking intergrain exchange coupling in magnets. (C) 2003 American Institute of Physics. |
