The strongest permanent magnets today contain a mix of the elements neodymium and iron. However, neodymium on its own does not behave like any known magnet, confounding researchers for more than half a century. Now Radboud University Nijmegen The Netherlands physicists have now shown that neodymium behaves like a so-called ‘self-induced spin glass,’ meaning that […]

Roman Morgunov from the Institute of Problems of Chemical Physics at the Russian Academy of Sciences and his colleagues have now developed a simple additive-based method for ensuring the stability of permanent magnets over time. They have developed methods to counter the spontaneous loss of magnetization, based on their understanding of the underlying physical phenomenon. […]

The European Union has begun to gather concern about the availability of rare earth elements.  The rare earth elements are important components in green energy products such as wind turbines and efficient automobiles. The demand for metals such as neodymium (Nd) and dysprosium (Dy) is increasing much faster than production. These metals are used in […]

Professor Thomas Schreflat is leading a team St. Pölten University of Applied Sciences in Austria showing that rare earth permanent magnets may contain local deformations in the crystal lattice of the material, resulting in a weakening of the magnetic force of the material in those areas.  Finding ways to minimize or eliminate the deformations would […]
