The bigausson model of high‐temperature superconductivity is generalized to three dimensions. The stability of the bigaussons is investigated and the possibility of a bigausson condensate is shown. The anisotropy for the following parameters of cuprate superconductors is calculated: coherence length, energy gap, and critical current density. The obtained results are in agreement with the experimental data for Y 1 Ba 2 Cu 3 O 7–δ .
