摘要: The spin structure and energy of ferromagnetic domain walls in Dy Tb have been calculated, using an iterative method which takes into account exchange interactions, magnetocrystalline anisotropy, magnetoelastic anisotropy. are found to be very thin (less than 20 atom layers) relatively high (∼10 erg/cm2), as compared the transition metals. An intrinsic coercive force for wall motion is predicted these walls; it analogous Peierls‐Nabarro on a dislocation, estimated order 1 kOe 30 Oe at absolute zero.
