Abstract
The mean-field theory of magnetic structure of cupric oxide is developed. It is shown that the different phases arising in this compound result from the high spacial anisotropy of the exchange interactions discussed earlier by Asbink and Norrby. The transition between the antiferromagnetic and incommensurate phases can be due to the effect of biquadratic exchange interactions.
