Intrinsic magnetic properties of (Nd1?xSmx)Fe11Ti

A series of (Nd1?xSmx)Fe11Ti alloys with the ThMn12 crystal structure have been fabricated and characterized in order to promote a strong uniaxial anisotropy NdFe11Ti without need nitrogenation. The compounds show small changes lattice parameters cell volume, as well Curie temperature spontaneous magnetization. field, however, rapidly increases incorporation Sm overcomes effect nitrogenation, reaching values>4 T for 30% content. Mössbauer spectroscopy indicates that quadrupole splitting is correlated magnetic anisotropy. These are good candidates permanent magnets, provided correct microstructure developed increase coercivity.
