Magnetic Structure of Neodymium
Journal of Applied Physics, 1964 Neutron diffraction measurements have been made on a single crystal of neodymium at temperatures between 1.6° and 20°K. The onset of magnetic ordering occurs at 19°K and the magnetic structure changes at 7.5°K. The crystal structure is hexagonal with a four-layer stacking sequence of type ABAC.

Effect of the surface magnetic anisotropy of neodymium atoms on the coercivity in neodymium permanent magnets [PDF]
Physical Review B, 2021 The Nd permanent magnet (${\mathrm{Nd}}_{2}{\mathrm{Fe}}_{14}\mathrm{B}$) is an indispensable material used in modern energy conversion devices. The realization of high coercivity at finite temperatures is an important issue. One of the important ingredients for controlling the coercive force is the surface property of magnetic grains.
