      abstract     = {We have studied the atomic and magnetic structure of the
                      dilute ferromagnetic semiconductor system (Ba,K)(Zn,Mn)2As2
                      through atomic and magnetic pair distribution function
                      analysis of temperature-dependent x-ray and neutron total
                      scattering data. We detected a change in curvature of the
                      temperature-dependent unit cell volume of the average
                      tetragonal crystallographic structure at a temperature
                      coinciding with the onset of ferromagnetic order. We also
                      observed the existence of a well-defined local orthorhombic
                      structure on a short length scale of ≲5Å, resulting in a
                      rather asymmetrical local environment of the Mn and As ions.
                      Finally, the magnetic PDF revealed ferromagnetic alignment
                      of Mn spins along the crystallographic c axis, with robust
                      nearest-neighbor ferromagnetic correlations that exist even
                      above the ferromagnetic ordering temperature. We discuss
                      these results in the context of other experiments and
                      theoretical studies on this system.},
