Abstract

In this paper, we present the results of the structural and magnetic properties of Fe_0.9-xCo_xZr_0.1 Alloys. X-ray diffraction indicates that this system crystallizes in the cubic BCC structure as a dominant phase and some minor phases. The cubic phase is associated with α-(Fe-Co) while the minor phases are associated with Fe-Zr intermetallic phase. Room temperature Mössbauer spectra of the alloy system indicate that iron is present in two magnetic sites and one minor non-magnetic site. One of the two magnetic sites is attributed to the α-(Fe-Co) phase in which Co is dissolved, and the other to Fe-Zr intermetallic phase. The minor non-magnetic site is attributed to the γ-Fe phase. The magnetic hyperfine field corresponding to the Fe-Co magnetic phase was found to increase with increasing cobalt concentration, which is due to the increase in the spin density at the Fe nucleus. A small decrease in the hyperfine field is observed for the Fe-Zr phase which can be due to the change in the chemical environment around the Fe atoms. The average isomer shift for this system is negative indicating an increase in the s-electron density at the Fe nucleus.
