Query: Spin-Triplet Vortex State in the Topological Superconductor CuxBi2Se3   We report on the observation of bulk superconductivity from dc magnetization
measurements in a cylindrical single crystal of CuxBi2Se3. The magnitude of the
magnetization in the Meissner state is very small and the magnetic-field
dependence of the magnetization just above the lower critical field Hc1 is very
different from those of usual type-II superconductors. We studied the character
of the vortex state theoretically in a spin-triplet pairing superconductor and
compared it with the experimental results. The results showed that, the
superconductivity observed in CuxBi2Se3 is consistent with the spin-triplet
pairing superconductivity with odd parity. We also observed a rapid relaxation
phenomenon of the superconducting diamagnetism.
