Crystal Field Interaction and Magnetic Order in GdBa/sub 2/Cu/sub 3/O/sub 7/
Description:
We report experimental data on the crystal field interaction of Gd ions with their environment in Gd/sub x/Eu/1-x/Ba/sub 2/Cu/sub 3/O/sub 7/. The ESR spectrum and a Schotiky anomaly in the specific heat of dilute samples indicate the existence of a crystal field splitting of the /sup 8/S/sub 7/2/ ground state of the Gd/sup 3 +/ ions of about 1.5K. Since the single ion energies involved are of the same order of magnitude as the energies associated with the magnetic ordering of the Gd moments in …
