Mössbauer spectroscopic studies of (Fe1−Ru )2P (x=0 and 0.02)

Abstract The Mossbauer spectroscopic measurements have been carried out on (Fe 1− x Ru x ) 2 P ( x =0 and 0.02) at T =5 and 300 K. The magnetic moment in Fe 2 P in the ferromagnetically ordered state has been estimated to be about 0.76 μ B and 1.97 μ B for Fe site I and II, respectively at T =5 K. For (Fe 0.98 Ru 0.02 ) 2 P, however, it is found that there are three sites I, II, and III, ordering antiferromagnetically, and the magnetic moments are estimated to be about 0.66 μ B and 1.89 μ B for Fe(I) and Fe(II), respectively.
