Conflicting results have been published as to the magnetic properties of this mineral, with M\\\"ossbauer spectroscopy indicating no magnetic ordering and density functional theory predicting an antiferromagnetic ground state, similar to the Fe-based high-temperature superconductors with which it is isostructural and for which it is known that magnetism is suppressed by strong itinerant spin fluctuations.
