Abstract
We have performed detailed 57Fe Mössbauer spectroscopy measurements on Ba0.75K0.25Fe2As2 single-crystal mosaics showing antiferromagnetic ordering below TN = 95 K with superconductivity below TC around 30 K. Analysis of the Mössbauer spectra shows a decrease in the magnetic hyperfine field but no change in the magnetic volume fraction below TC. This indicates coexistence of magnetism and superconductivity in these compounds.
