Ferromagnetic Laves phase intermetallics doped with sp impurities: A Mössbauer study of Zr(Fe1−xSix)2

Abstract

The effect of Si on the hyperfine parameters of the pseudobinary compounds Zr(Fe1−xSix)2 is studied by Mossbauer spectroscopy in the C15 phase (x≦0.17). In these pseudobinaries, two magnetic sites of the pure compound coexist with a third site associated with the impurities. The local effects in Zr(Fe,Si)2 are qualitatively discussed, together with the observed trends of the hyperfine parameters. A comparison with Zr(Fe,Al)2 compounds is also presented.
