Actinide and lanthanide binary nitrides (AnN, LnN), are isostructural cubic compounds relevant to next-generation nuclear fuels which require detailed understanding regarding their oxidative degradation for safe disposal, yet a systematic comparative description remains. Herein, the room- and high-temperature oxidation behaviour of U3+N and Ln3+N (Ln = Pr, Nd, Gd, Tb, Dy, Ho, Tm and Lu) compounds is examined via a combination of X-ray diffraction, electron microscopy, thermogravimetric, and X-ray absorption spectroscopy analysis.

Magnetic singularities known as Bloch points (BPs) present a fundamental challenge for micromagnetic theory, which is based on the assumption of a fixed magnetization vector length. Due to the divergence of the effective field at a BP, classical micromagnetics fails to adequately describe BP dynamics [...]
