We give new examples of algebraic integral cohomology classes on smoothprojective complex varieties that are not integral linear combinations ofclasses of smooth subvarieties. Some of our examples have dimension 6, thelowest possible. The classes that we consider are minimal cohomology classes onJacobians of very general curves. Our main tool is complex cobordism.Comment: 11 pages, v3: final versio
