Research Abstract

Detailed structure analysis by synchrotron x-ray diffraction experiments and the electronic structure calculations demonstrate that the novel ferromagnetic metal-insulator transition in K2Cr8O16 is caused by a Peierls instability in the quasi-one-dimensional column structure made of four coupled Cr-O chains running in the c direction, leading to the formation of tetramers of Cr ions below the transition temperature. This provides a rare example of the Peierls transition of fully spin-polarized electron systems.
