Abstract
We present an investigation of the magnetic properties of the ludwigite . This material is an oxyborate that presents in its crystalline structure subunits in the form of walls where the transition metal ions are located. Our Mössbauer, ac susceptibility, and magnetization measurements show that Fe and Ni ions form two independent subsystems in this material down to K. We explain this behavior in terms of a hierarchy of interactions.
