Crystal field interaction and magnetic order in GdBa/sub 2/Cu/sub 3/O/sub 7/

Creators

Description

We report experimental data on the crystal field interaction of Gd ions with their environment in Gd/sub x/Eu/1-x/Ba2Cu3O7. The ESR spectrum and a Schotiky anomaly in the specific heat of dilute samples indicate the existence of a crystal field splitting of the 8S/sub 7/2/ ground state of the Gd3+ 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 GdBa2Cu3O7 (T/sub N/ = 2.24K) we analyze the effects of the crystal field interaction on the magnetic transition. 10 refs., 4 figs
