Keywords:Orbital magnetic moments, inverse magneto-striction effect

We have developed the electric-field (E) induced x-ray magnetic circular dichroism (EXMCD) technique in order to apply E to ferroelectric BaTiO₃ substrate, which tunes the interfacial lattice constants of the Ni/Cu multilayers on BaTiO₃. In this study, we discuss the microscopic origin of inverse magneto-striction effects concerning the orbital magnetic moments by using the EXMCD and the first-principle calculation.
