High magnetic fields revive superconductivity in nickelates
Scientists from the National University of Singapore (NUS), in collaboration with Los Alamos National Laboratory in the United States, have uncovered that a class of nickel-based materials known as samarium (Sm)-based infinite-layer nickelates can regain their superconducting abi
The discovery of superconductivity in nickelates is a significant breakthrough in the field of materials science. For years, researchers have been searching for new classes of superconducting materials that can efficiently conduct electricity with zero resistance. The fact that samarium-based infinite-layer nickelates can regain their superconducting ability under high magnetic fields suggests that these materials have a complex and tunable electronic structure.
This finding is particularly exciting because it challenges our current understanding of superconductivity in different materials. Nickelates are considered a promising alternative to cuprates, which are the only known class of high-temperature superconductors. The ability to manipulate superconductivity in nickelates using external magnetic fields opens up new avenues for research into the underlying mechanisms of superconductivity. Furthermore, this discovery has potential implications for the development of new technologies, such as high-energy applications and advanced medical equipment.
As researchers continue to explore the properties of nickelates, it will be interesting to see whether these materials can be optimized for practical applications. One key area to watch is the synthesis of new nickelate compounds with improved superconducting properties. Additionally, experimental studies of the electronic structure and magnetic behavior of these materials will be crucial in understanding the underlying physics. The collaboration between the NUS and Los Alamos National Laboratory is a great example of international research efforts that can drive innovation and advancement in this field.
