Abstract
We present thermodynamic, structural, and transport measurements on Ba (Fe0.973 Cr0.027) 2 As2 single crystals. All measurements reveal sharp anomalies at ∼112K. Single crystal x-ray diffraction identifies the structural transition as a first order, from the high-temperature tetragonal I4/mmm to the low-temperature orthorhombic Fmmm structure, in contrast to an earlier report.
