Notes:
The susceptibility of an ErBa2Cu3O6 single crystal was measured at 2 K〈T〈100 K. The low-temperature (T〈10 K) data yield g(parallel)=5.39 and g⊥=7.45. The shapes of the susceptibility curves are well explained by the dipolar fields, calculated for the Er3+ ions in the layered structure of the sample, and by a small contribution of exchange fields. Extending the calculations to the antiferromagnetic state of ErBa2Cu3O6 shows that this material is well described as a two-dimensional dipolar antiferromagnet. The dipolar field calculations are also applied to DyBa2Cu3O6 and GdBa2Cu3O6 and are shown to be compatible with the magnetic structure of these materials. © 1994 American Institute of Physics.
