Here, we show using thermodynamic probes that the phase diagram of the first discovered, and highest Tc, 122-type material, Ba1-xKxFe2As2 is in fact much richer than previously reported. Inside the usual stripe-type magnetic order with C2-symmetry, we find a small pocket of a tetragonal, C4-symmetric phase, which surprisingly reverts back to the C2-phase at or slightly below the superconducting transition.","authors_text":"A.
