Abstract
It is shown that in (3 + 1)-dimensional space-time the recently proposed supersymmetric models of disordered systems can have finite-energy solitonlike solutions. As a a consequence, it is suggested that the lower critical dimension of a ferromagnet in a quenched random magnetic field is .
