Gadolinium in lutetium fluoride—an electron paramagnetic resonance study
Gadolinium (Gd 3+) in Czochralski-grown lutetium fluoride (LuF 3) has been investigated by electron paramagnetic resonance (EPR). Detailed analysis of the EPR angular dependencies reveals that Gd 3+ entered substitutionally for Lu 3+ in monoclinic C s site symmetry. The Lu site seems to be more dist...

Summary: | Gadolinium (Gd
3+) in Czochralski-grown lutetium fluoride (LuF
3) has been investigated by electron paramagnetic resonance (EPR). Detailed analysis of the EPR angular dependencies reveals that Gd
3+ entered substitutionally for Lu
3+ in monoclinic
C
s
site symmetry. The Lu site seems to be more distorted by the Gd ion as compared to the Y site in YF
3. The zero-field splitting of the ground state b
2
0 is −1.8372
GHz which is more than twice compared to that of Gd
3+ in host crystals of LaF
3, in which gadolinium has the same co-ordination number. The results of the fine structure analysis are compared to a similar study in the iso-structural host YF
3. The obtained results seem to be in contrast to the superposition model. |
