摘要：

Magnetic structure of KFeS2 - a spin analog of the oxidized two iron ferredoxins - was determined by the neutron diffraction method. Spins are antiferromagnetically coupled along the c-axis chain, and they make ferromagnetic sheets in the planes containing a and b axes below the transition temperature of 250.0 ± 0.5 K. The iron moment of 2.43 ± 0.03 μB lies in the a-c plane and is canted by 125.3 ± 0.7 degrees from a-axis at 4.2 K. © 1979.
