Overview Scientists have achieved a breakthrough in understanding magnetism by discovering a new type of magnetism in a rare-earth compound, specifically neodymium nitride (NdN) . This new form of magnetism, arising from the orbital angular momentum of electrons , holds promise for advancements in quantum and spintronic technologies . The research envisions a new class of materials that can be tuned to design faster and more energy-efficient magnetic and quantum devices. Key Developments Discovery of Orbital-Driven Magnetism The study, led by the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) , demonstrated that single-crystalline grown thin films of neodymium nitride (NdN) exhibit ferromagnetism originating from the orbital angular momentum of electrons. This marks a significant departure from conventional magnetic behavior, which is primarily driven by the electron's spin. Implications for Orbitronics This landmark finding, published in ACS Nano , opens new possibilities in the emerging field of “orbitronics” . Orbitronics aims to harness the orbital motion of electrons for future quantum and spintronic technologies, potentially leading to next-generation information and memory technologies. Advanced Techniques and Analysis The research team, led by Prof. Bivas Saha from JNCASR , employed advanced thin-film growth and characterization techniques, complemented by electronic structure analysis. This approach revealed how crystal symmetry, electronic hybridization, and rare-earth orbital states together stabilize this unique orbital-driven magnetism.
