Superconducting Magnetics: Emerging Innovations and Prospective Uses
In the realm of scientific discovery, superconducting materials are making waves with their potential applications in various sectors, including energy, transportation, and medicine.
Superconductors, materials that can conduct electricity with zero resistance, are being explored for use in high-speed transportation, medical devices, and energy storage. One such example is the creation of high-speed transportation systems, such as magnetic levitation trains, enabled by superconducting materials.
In the energy sector, the future prospects for the new generation of superconductors are promising, with significant advancements expected in the coming years. Current advancements in rare-earth barium copper oxide (RBa2Cu3O7-x or REBCO) focus on its use in high-temperature superconducting (HTS) tapes for powerful, compact, high-field magnets. These HTS magnets are critical in energy applications, especially nuclear fusion reactors. For instance, REBCO tapes are key components in the magnets for compact tokamak fusion devices such as Commonwealth Fusion Systems’ SPARC and planned ARC reactors aimed to produce net fusion energy and commercial fusion power in the 2020s and 2030s, respectively.
High-speed transportation, medical devices, and energy storage are just a few examples of the exciting new possibilities for the application of the new generation of superconductors. However, challenges and limitations in the development of these materials include scalability, stability, and cost.
In the medical field, superconducting materials could enable the creation of high-capacity energy storage systems, such as supercapacitors, and improve MRI and other high-field imaging modalities. Researchers have successfully created superconducting graphene-based materials, which hold future potential for compact, energy-efficient electronic components in fields ranging from next-generation transportation systems to advanced medical imaging and diagnostics.
Iron Selenide (FeSe) is another superconductor with a high critical temperature (Tc) of up to 46 K (-227°C). While current advancements in FeSe are not as widely commercialized as REBCO, it holds promise due to its simple structure and ability to exhibit superconductivity under ambient pressure or with interface engineering. This makes it a candidate for future quantum devices and sensors relevant to energy and possibly medical technologies.
