Abstract

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 to)=5.39and g(perpendicular to) =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 contributionof exchange fields. Extending the calculations to the antiferromagnetic state of ErBa2Cu3O6 shows that this material is well described as atwo-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. (C) 1994 American Institute of Physics.
