Structural and Magnetic Properties of Pseudobinary System (Zr1-xNbx)Fe2

This is the authors' abstract. We don't add key points for this paper.

In pseudobinary system (Zr 1- x Nb x )Fe 2 , the crystal structure is MgCu 2 type for x ≦0.3, MgZn 2 type for x >0.5 and six layers structure for 0.35< x <0.5. The compounds show ferromagnetism for x ≦0.4, antiferromagnetism for 0.4< x ≦0.5 and (Pauli) paramagnetism for x >0.5. It is concluded with reference of the Mössbauer experiment that the magnetic moment of iron is far larger in MgCu 2 structure than in MgZn 2 structure. Dominant factors to affect the magnetic polarization of iron are the arrangement of the surrounding atoms as well as the magnetic polarization of the surrounding iron atoms.
