In the preceding Comment, the energy of the system is expanded at a van Hove singularity of one band as a function of changes in the field, the magnetization, and the Fermi energy. Unfortunately, not all the derivatives are properly defined at a van Hove singularity. This leads to the erroneous conclusion that the susceptibility is finite at the critical point. The correct result is that {ital M}{proportional to}({ital H}{minus}{ital H}{sub {ital c}}){sup 1/2}, in analogy to a Prokovsky-Talapov transition.
