All data are in delimited ASCII text format.
The data were collected in order to examine the relationship between structural chemistry of these new compounds and their electronic properties. The latter are evident in both the electronic conductivity (i.e. metal vs insulator) and in the magnetic behaviour.
These neutron diffraction data determine the crystal structure distortions in these double perovskites. The arrangement of magnetic spins is indicated by the Bragg scattering of the neutron wave. The diffraction files are in the standard GSAS format.
The magnetic measurements indicate the magnetic moment per weighed amount of the sample in a dc magnetisation measurement conducted using a SQUID magnetometer. These files are in the standard Quantum Design MPMS output.
Transport data record the temperature, conductivity and applied magnetic field.
The data that are presented in the J Mater Chem C article Coomer, Corr and Cussen, 2017.
