Keywords:Skyrmion, Topological Hall effect

Topological non-coplanar spin textures, including magnetic skyrmions, having real space berry phase, can induce a special electron scattering called topological Hall effect. Authors have observed skyrmions in β-Mn type chiral magnets Fe_2-xPd_xMo₃N by Lorentz-TEM. The Pd concentration and temperature dependence of topological Hall effect in Fe_2-xPd_xMo₃N epitaxial thin films will be reported.
