      abstract     = {Neodymium-based permanent magnets are fundamental to modern
                      technologies, underpinning high-performance applications in
                      electronics, renewable energy, and advanced medical systems.
                      Among emerging neodymium compounds, neodymium nitride (NdN)
                      has attracted significant attention due to its unique
                      electronic structure, where strongly localized 4f orbitals
                      and strong spin–orbit coupling are anticipated to drive
                      exceptional magnetic behavior. Here, we show conclusive
                      experimental evidence of orbital angular momentum-driven
                      ferromagnetic ordering and prominent magnetic anisotropy in
                      epitaxial, near-stoichiometric NdN thin films synthesized
                      using ultrahigh vacuum deposition techniques. Magnetization
                      and X-ray magnetic circular dichroism measurements reveal a
                      dominant 4f orbital moment of 5.14 μB, contributing to a
                      total magnetic moment of 2.43 μB per formula unit at 4 K,
                      close to the first-principles density functional theory
                      calculated values. Complementary synchrotron-radiation
                      photoelectron spectroscopy, along with the theoretical
                      calculations, uncovers occupied 4f states ∼6.4 eV below
                      the Fermi level, contributing to the orbital-driven
                      ferromagnetism in NdN. Moreover, the high crystalline
                      quality of the NdN films is further supported by the
                      structural characterization and vibrational properties. The
                      intrinsic orbital angular momentum-driven magnetism of NdN
                      positions it as a promising platform for next-generation
                      orbitronic devices beyond conventional spintronics.},
