A study on the relationship of magnetic moments orientation in L10FePt network nanostructured film by electron energy-loss magnetic chiral dichroism using semi-core excitation spectra

Autor: Hitoshi Makino, Ján Rusz, Jian Wang, Diego Turenne, Masahiro Ohtsuka, Yukiko K. Takahashi, Hermann A. Dürr, Shunsuke Muto

In this study, we applied electron energy-loss magnetic chiral dichmism (EMCD), an electron counterpart of X-ray magnetic circular dichmism (XMCD), to a network nanostructured FePt L1(0) ordered alloy film to examine the relative orientation of magne
