Magnetism plays an important role in superconductivity. Specifically, there must be a complete absence of magnetic ordering for superconductivity to occur. It is known that BaFe2As2 becomes superconducting only after being doped with nickel or cobalt. Doping lowers the Curie temperature of BaFe2As2 such that it never becomes magnetically ordered. Introducing nickel or cobalt changes the electron density which has a strong on magnetization. We can learn about the transition into superconductivity by studying the magnetic properties of BaFe2As2. We study the iron sites of BaFe2As2 which are an indicator of the magnetism present in our sample. Mossbauer spectroscopy is the tool we use to measure the strength of the hyperfine field which is proportional to the magnetization. The strength of the hyperfine field is also a function of temperature. As we raise the temperature we see relaxation of the sextet as we approach the Curie temperature. Mossbauer spectra are fitted using a two sextet model which indicates there are two distinct iron sites in the lattice. This is unexpected due to symmetry of the lattice. One possible explanation for our two sextet model is spin polarization of electron density. A non-uniform spatial distribution of uncompensated electron spin, also called a spin density wave, would cause iron sites in a symmetric lattice to experience different magnitudes of hyperfine field.
