There are two bits to this, all superconducting materials are diamagnetic it’s simply the property that a material creates a magnetic field that is opposed to the applied magnetic field. All materials exhibit this property but it’s not strong enough to levitate. One thing that strongly diamagnetic materials tend to have is very I high resistance, and this material has both low resistance and this diamagnetic property. Something very interesting.
