Title: Magnetic and crystallographic properties of ZrM2-δZn20+δ (M=Cr–Cu)

Abstract

Single crystals of the cubic Laves ternaries ZrM2-δZn20+δ (M=Mn, Fe, Co, Ni and Cu, 0 ≤ δ ≤ 1) have been synthesized in this paper using a self-flux method. The magnetic properties of these compounds were compared with structurally similar cubic binaries ZrM2 (M=Mn, Fe, Co, Ni and Cu). A transition from local to itinerant moment magnetism was observed for M=Fe and M=Mn, while all other ternaries exhibit weakly para- or diamagnetic behavior. The local-to-itinerant crossover can be explained by a nearly two-fold increase of the M–M bond length dM–M in ZrM2-δZn20+δ compounds, as compared with the ZrM2 binaries. Additionally, we report two new compounds in this series ZrCrZn21 and ZrCu2Zn20. Finally, analysis of crystallographic and magnetic trends in these materials will aid in understanding of magnetism in general and 3d intermetallics in particular.
