This question hasn't been answered yet Ask an expert. Austenitic stainless steels are usually described as 'non-magnetic' since their response to a hand-held magnet is negligible. Electron microscopy confirmed the elemental composition and revealed the microstructure to consist of two spinodally decomposed phases. CeRh 3 B 2, crystallizing in the hexagonal CeCo 3 B 2-type structure (P6/mmm), is a ferromagnet with the highest Curie temperature T C of ≃120 K for any compound of Ce with other non-magnetic elements. In this study, the ordered FeRh 0.95 Ir 0.05 alloy thin films were deposited by sputtering directly onto substrates heated above 250°C. So the bond order of B2 is equal to 1, which you can get by drawing the molecular orbital diagram and performing the equation Bond Order = .5 * (# of bonding electrons - # of antibonding electrons).
