The reason that superconductors levitate it that they are perfectly diamagnetic. There are other materials that are strongly diamagnetic, such as bismuth , that can be made to levitate but normally the effect is not stable enough without additional components, such as being sandwiched between two powerful magnets. However Pyrolytic carbon will levitate , at room temperature, above a strong enough magnet in the same way as a superconductor would.
