Pressure-induced stabilization and insulator-superconductor transition of BH.
Diborane (B(2)H(6)), a high energy density material, was believed to be stable in a wide P, T interval. A systematic investigation of the B-H system using the ab initio variable-composition evolutionary simulations shows that boron monohydride (BH) is thermodynamically stable and can coexist with solid B, H(2), and B(2)H(6) in a wide pressure range above 50 GPa. B(2)H(6) becomes unstable and de...
متن کاملPressure-induced superconductor-insulator transition in the spinel compound CuRh2S4.
We performed resistivity measurements in CuRh2S4 under quasihydrostatic pressure of up to 8.0 GPa, and found a pressure-induced superconductor-insulator transition. Initially, with increasing pressure, the superconducting transition temperature T(c) increases from 4.7 K at ambient pressure to 6.4 K at 4.0 GPa, but decreases at higher pressures. With further compression, superconductivity in CuR...
متن کاملQuasilinear quantum magnetoresistance in pressure-induced nonsymmorphic superconductor chromium arsenide
In conventional metals, modification of electron trajectories under magnetic field gives rise to a magnetoresistance that varies quadratically at low field, followed by a saturation at high field for closed orbits on the Fermi surface. Deviations from the conventional behaviour, for example, the observation of a linear magnetoresistance, or a non-saturating magnetoresistance, have been attribut...
متن کاملEffect of hydrostatic pressure on the ambient pressure superconductor CePt3Si
We studied the evolution of superconductivity (sc) and antiferromagnetism (afm) in the heavy fermion compound CePt3Si with hydrostatic pressure. We present a pressure-temperature phase diagram established by electrical transport measurements. Pressure shifts the superconducting transition temperature, Tc, to lower temperatures. Antiferromagnetism is suppressed at a critical pressure Pc ≈ 0.5 GPa.
