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 4 p 6 to 4 p 5 (4 d +5 s ) 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 0.01 µ B /ion.
