Pressure-induced superconductor-insulator transition in the spinel compound CuRh2S4.

چکیده
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 CuRh2S4 disappears abruptly at a critical pressure P(SI) between 5.0 and 5.6 GPa, when it becomes an insulator.

Electronic evidence of an insulator-superconductor crossover in single-layer FeSe/SrTiO3 films.
In high-temperature cuprate superconductors, it is now generally agreed that superconductivity is realized by doping an antiferromagnetic Mott (charge transfer) insulator. The doping-induced insulator-to-superconductor transition has been widely observed in cuprates, which provides important information for understanding the superconductivity mechanism. In the iron-based superconductors, howeve...
متن کاملExotic properties of spinel oxide superconductor Li1þxTi2O4
The polycrystalline Li1þxTi2O4 has intricate physical behaviors in normal and superconducting state. High-resolution X-ray diffraction shows that it is the pure spinel phase and there is no structural phase transition down to 20 K. In addition to the field-induced broadening of RðT Þ near the superconducting regime, an anomalous upturn in RðT Þ appears near the transition temperature when magne...
متن کاملPressure-induced metal-insulator and spin-state transition in low-valence layered nickelates
Ab initio calculations predict a metal-insulator transition at zero temperature to occur in La4Ni3O8 at moderate pressures as a result of a pressure-induced spin-state transition. The spin-state transition that is seen at 105 K at ambient pressure, from a low-temperature high-spin state to a high-temperature low-spin state, has been observed to be shifted to lower temperatures as pressure is ap...
متن کاملDisappearance of nodal gap across the insulator-superconductor transition in a copper-oxide superconductor.
The parent compound of the copper-oxide high-temperature superconductors is a Mott insulator. Superconductivity is realized by doping an appropriate amount of charge carriers. How a Mott insulator transforms into a superconductor is crucial in understanding the unusual physical properties of high-temperature superconductors and the superconductivity mechanism. Here we report high-resolution ang...
متن کاملMagnetic-Field Induced Superconductor-Insulator Transition in the La2-xSrxCuO4 System.
The magnetoresistance of underdoped La22xSrxCuO films with x 0.048 and 0.051 is studied in magnetic fields up to 8.5 T and at temperatures down to 30 mK. The results indicate that the magnetic-field induced superconductor-insulator (SI) transition is qualitatively different from the reentrant transition described for indium oxide and interpreted as leading to a “bosonic insulator” phase. The ...
