Neutron diffraction study of Sr2FeCoO6, SrLaFeCoO6 and La2FeCoO6
Double perovskites are a fascinating material class with a lot of functional properties. Multiferroicity, magneotcapacitance, magnetoresistance, different magnetic ground states including spin-glass and three dimensional quantum magnetism have been either experimentally observed or theoretically proposed for these materials. We propose to do polarized neutron diffraction study on the double perovskites Sr2FeCoO6, SrLaFeCoO6 and La2FeCoO6 as a function of temperature in the range 1.5 – 300 K in fine temperature steps. The XYZ polarization analysis available on the polarized diffractometer D7 will enable us to separate magnetic and nuclear scattering absolutely essential in order to interpret the data properly. We request 7 days of neutron beam time on D7 for this.
