Abstract

We report the magnetic properties of [Co(NH3)6][FeCl6], a bimetallic salt showing an fcc antiferromagnetic frustrated lattice. The temperature dependence of the ac magnetic susceptibility, measured on a single crystal, indicates antiferromagnetic ordering at Tc = 0.50 ± 0.05 K, with a maximum at 0.80 ± 0.01 K. The analysis of the data gives values of Jnn/k = −0.068 ± 0.001 K for the first-neighbor interactions and Jnnn/k = 0.005 ± 0.001 K for the second-neighbor ones. © 1990, American Chemical Society.
