Description
The compound YbB2 has been reported to order anti-ferromagnetically at temperatures around 5.6 K. This transition was verified from heat capacity data taken in different magnetic fields by our Quantum Design PPMS system. X-ray diffraction measurements have been performed using this sample under different pressures at the APS facility in Argonne National Laboratory. A sudden change in resistivity measurements of the sample indicated a possible structural phase transition around 3 GPa. The data indicates the YbB2 compound is not responsible for the anomaly.
