Josephson tunneling in LiTi 2O 4
Abstract
Josephson point contact tunneling between LiTi 2O 4 and Nb reveals, under K-band microwave radiation. Shapiro steps of spacing approximately hv/2 e. This appears to confirm that superconductivity in this material has s-wave pairing, of interest in connection with recent suggestions of Kulik and of Ranninger.
