Rattling-enhanced superconductivity in ScV2Al20 intermetallic cage compounds

Abstract: Conventional superconductors are robust diamagnets that expel magnetic fields through the Meissner effect. It would therefore be unexpected if a superconducting state would support spontaneous magnetics fields. Such broken time-reversal symmetry states have been suggested for the high-temperature superconductors, but their identification remains controversial. Our recent µSR study on the caged type R5Rh6Sn18 (R = Lu, Sc and Y) superconductors reveals TRS broken superconductivity due to strong spin orbit coupling. The interesting physical behaviour that is often observed in cage-type structures frequently originates from the so-called “rattling” effect. Recently Winiarski et. al. reported rattling-enhanced superconductivity in ScV2Al20 with Tc = 1.00 K. We propose to study the role of rattling mode in the superconducting state using ZF and TF muSR measurements on the MUSR spectrometer.
