Abstract
In two recent publications [Phys. Rev. B 60, 7496 (1999); 63, 054508 (2001)] Kuplevakhsky has questioned the existence and stability of isolated Josephson vortices in layered superconductors. He argued that “vortex planes” rather than isolated vortices correspond to “unconditional minimum” of Gibbs free energy and ruled out “any possibility of single Josephson vortex penetration.” In this comment, I disprove those statements and demonstrate that isolated Josephson vortices penetrate layered superconductors and have considerably lower energy than vortex planes.
