Abstract

Natural silicates often contain small amounts of 3d transition metal ions in octahedral sites, which possess a magnetic moment due to unpaired 3d electrons. When the concentration of 3d ions is sufficiently high for them to couple magnetically via exchange interactions, there may be a phase transition to a collective, magnetically ordered state at low temperatures.
