Is magnetic frustration behind the tetragonal-to-orthorhombic transition in t...
It has been argued that the tetragonal-to-orthorhombic structural transition found in all the parent phases of the Fe-pnictide superconductors is driven by frustration, and... -
Spin dynamics in FeSi
At low temperatures FeSi is a non-magnetic insulator, but becomes a metallic paramagnet for T > 300K. It has been proposed to be a Kondo insulator in which local electron...
