Micromagnetic analysis of pinning-hardened nanostructured, nanocrystalline Sm_2Co_(17) based alloys

摘要

In Sm(Co_(bal)Cu_(0.07)Fe_(0.22)Zr_0.04))_(7.4) the chemical composition of the 2:17 cells and the 1:5 cell walls has been analysed by high-resolution TEM-EDX for different annealing stages. From the measured Cu-profile the profile of the first anisotropy constant has been determined and applied to determine the pinning of domain walls at the phase boundary.
