Using MR techniques at the National High Magnetic Field Laboratory in Tallahassee, Fla., Halperin and his team studied Bi-2212, one of the "darlings" of superconductivity. To measure its properties, they put the rare isotope oxygen-17 into a crystal of Bi-2212, with the isotope acting as a probe, much like a fluorescent dye. They then determined the phase diagram of the material where superconductivity is stable, which showed high temperature and high magnetic field could not be achieved together.
How to make the bismuth compound into the appropriate wires and configure them into a magnet still has to be determined

30 teslas is good, but ideally the material should be able to generate a 60T tesla field. This is necessary to realize a potential propulsion application if the Heim Quantum Theory turns out to be for real.
