We report the results of the low-temperature specific heat measurements of the single crystalline β -pyrochlore oxide superconductors AOs2O6 (A=K, Rb, and Cs) under high pressure up to 13 GPa. We find that superconducting transition temperature (Tc)
Rattling-induced superconductivity in the beta-pyrochlore oxide RbOs2O6 is investigated under high pressures up to 6 GPa. Resistivity measurements in a high-quality single crystal show that the superconducting transition temperature Tc increases grad

The superconducting properties of two β-pyrochlore oxides, CsOs 2 O 6 and RbOs 2 O 6 , are studied by thermodynamic and transport measurements using high-quality single crystals. It is shown that the character of superconductivity changes systematic

High-pressure resistivity measurements are performed on a high-quality single crystal of the β -pyrochlore oxide KOs2O6 in the pressure range of 1.0 to 5.0 GPa. The superconducting transition temperature T c increases slightly from 9.6 K at ambient

We develop a physical understanding for how anhamonicity of lattice vibration affects transition temperature, \(T_{\text{c}}\), of superconductivity mediated by phonons, via specific heat measurements on β-pyrochlore oxide superconductors under high

Rattling-induced superconductivity in the {\beta}-pyrochlore oxide KOs2O6 is investigated under high pressure up to 5 GPa. Resistivity measurements in a high-quality single crystal reveal a gradual decrease in the superconducting transition temperatu
