A semi-infinite Hubbard lattice of Anderson “impurities” with antiferromagnetic ordering of the inner layers is examined. The magnetization is analyzed for three models of magnetic ordering in the near-surface layers. The cases of zero and finite temperatures are examined. The possibility is discussed of a surface magnetic phase transition of the first kind.
