X-ray dichroism studies of magnetic anisotropies: Transcript
in ferromagnetic thin films The 9th Vacuum and Surface Science Conference of Asia and Australia VASSCAA9 August 1316 2018 Sydney Australia Atsushi FUJIMORI University of Tokyo Xray dichroism studies of magnetic anisotropies . In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir Energy .
