Structural and magnetic aspects of the metal insulator transition in Ca${}_{2-x}$Sr${}_x$RuO${}_4$

O. Friedt, M. Braden, G. Andre +3

The phase diagram of Ca${}_{2-x}$Sr${}_x$RuO${}_4$ has been studied by neutron diffraction on powder and single-crystalline samples. The experiments reveal antiferromagnetic order and st…
