The NdFe12Nx compound with a ThMn12 structure (space group I4/mmm) was successfully synthesized by nitriding an NdFe12 layer grown on a W underlayer on a single-crystalline MgO(001) substrate. The c-axis expanded from 0.480 to 0.492 nm while the a-axis showed a slight contraction from 0.852 to 0.849 nm after the nitriding. Excellent intrinsic hard magnetic properties of μ0Ms ≈ 1.66 ± 0.08 T, μ0Ha ≈ 8 T, and Tc ≈ 550 °C, which are superior to those of Nd2Fe14B, were obtained.

By taking advantage of novel materials, researchers have produced nanolasers that can be switched on and off with a magnetic field.
For the first time, researchers have visualized topological 'defects within defects' in a chiral magnetic thin film using electron microscopy.
