Abstract
The magnetic susceptibility of Ce:Gd3Sc3Al3O12 (Ce:GSAG) and Ce:La3Lu2Ga3O12 (Ce:LLGG) has been studied in the temperature range from 15 to 293Â K. Both the Ce-doped garnets Ce:GSAG and Ce:LLGG show anti-ferromagnetic ordering at 18 and 27Â K, respectively. Crystal electric field split energy levels have been used to calculate the magnetic susceptibility following Van Vleck's model. The calculated susceptibility values reasonably agree with the experimental susceptibility data of Ce:LLGG but differ for that of Ce:GSAG system. Contribution from long-range ordering between Ce and Gd ions for anomaly in Ce:GSAG system is speculated.
