STRUCTURAL AND MAGNETIC PROPERTIES OF PSEUDOBINARY SYSTEM (ZR1-XNBX)FE2

In pseudobinary system (zr1-xNbx)Fe2, the crystal structure is MgCu2 type for x≦0.3, MgZn2 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 jc>0.5. It is concluded with reference of the Mössbauer experiment that the magnetic moment of iron is far larger in MgCu22 structure than in MgZn2 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. © 1969, THE PHYSICAL SOCIETY OF JAPAN.
