Abstract
We present thermodynamic, structural, and transport measurements on Ba(Fe0.973Cr0.027)(2)As-2 single crystals. All measurements reveal sharp anomalies at similar to 112 K. 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.
