Determination of the zirconium site in zirconium-substituted Nd(Fe, Mo, Zr)12 compounds

The NdFe10.5Mo1.5-xZrx (x = 0.25,0.50) and Nd0.5Pr0.5Fe10.5-xMo1.5Zrx (x = 0, 0.25, 0.75, and 1.00) intermetallic compounds with ThMn12-type structures were successfully synthesized. Their structures were investigated by using powder X-ray diffraction. It is found that Zr is incorporated as a substi...

Description
Summary:The NdFe10.5Mo1.5-xZrx (x = 0.25,0.50) and Nd0.5Pr0.5Fe10.5-xMo1.5Zrx (x = 0, 0.25, 0.75, and 1.00) intermetallic compounds with ThMn12-type structures were successfully synthesized. Their structures were investigated by using powder X-ray diffraction. It is found that Zr is incorporated as a substituent for Nd/Pr in the structure of the two series, and the occupation of Zr is influenced by the prepared composition of Fe and the third element Mo. The effects of Zr on the magnetic properties were also studied.
