Abstract
Almost every element substituting Fe in Nd2Fe14B lowers the magnetocrystallined anisotropy. The effect on the ordering temperature Tc is different : in particular Al and Ni reduce Tc, whereas Si, Ga and Co increase Tc. Mössbauer experiments show that the Fe atoms are substituted in a non random manner. This is supported by the different magnetic properties due to the various substituents.
