摘要: Abstract We report the results of low temperature specific heat β -pyrochlore oxide superconductors RbOs 2 O 6 and KOs under high pressure. The superconducting transition T c monotonically increases with increasing pressure then abruptly vanishes at 6.0 GPa. Similar abrupt vanishment is also observed in 5.2 GPa. Under above 5.8 GPa, other two anomalies are found instead that superconductivity for . It suggested destruction appearance important to understand origin this system.
