Hexagonally structured MnRuP was studied under high pressure up to 35 GPa from 5 to 300 K using synchrotron x-ray diffraction. We observed that a partial phase transition from hexagonal to orthorhombic symmetry started at 11 GPa. The new and denser orthorhombic phase coexisted with its parent phase for an unusually long pressure range, ΔP≈50GPa. We attribute this structural transformation to a magnetic origin, where a decisive criterion for the boundary of the mixed phase lies in the different distances between the Mn-Mn atoms. In addition, our theoretical study shows that the orthorhombic phase of MnRuP remains steady even at very high pressures up to ∼250GPa, when it should transform to a new tetragonal phase.
Article no. 214103. The angle-dispersive x-ray diffraction measurements were performed at HPCAT (Sector 16-BM-D) and high-pressure x-ray-absorption experiments were performed at XSD (Sector 20-BM-B) of the Advanced Photon Source, a US Department of Energy (DOE) Office of Science user facility operated by Argonne National Laboratory (ANL) under Contract No. DE-AC02-06CH11357. HPCAT operation is supported by DOE-NNSA under Award No. DE-NA0001974, with partial instrumentation funding by NSF. XSD operation is supported by the DOE and the Canadian Light Source.
