G. Kanatzidis, and L. H. Greene We use point-contact spectroscopy (PCS) to probe A E Fe 2 A s 2 ( A E =Ca, Sr, Ba ) and Fe 1+y Te . For A E =Sr,Ba we detect orbital fluctuations above T S while for A E =Ca these fluctuations start below T S . Co doping preserves the orbital fluctuations while K doping suppresses it. The fluctuations are only seen at ... [Phys. Rev. B 85, 214515] Published Mon Jun 18, 2012
