- 論文の詳細を見る
Magnetic circular dichroism (MCD) of Y_3 Fe_5 O_<12> (YIG) was measured in the vacuum ultraviolet region between 22 eV and 40 eV by use of a polarizing undulator with crossed and retarded magnetic fields. Strong MCD features were observed for the inner core transitions of Y^<3+> from the 4p^6 to 4p^5 (4d+ 5s) levels, even though its ground state has J=0. It is suggested that the 'nonmagnetic' Y^<3+> ion in a ferrimagnetic YIG lattice has an induced magnetic moment on the order of 0.01μ_B/ion.
