摘要

We measure the ac susceptibility of single-crystal eCoIn(5) in dc field parallel to the c axis. We find further evidence for a high-field phase transition within the superconducting phase in this orientation. We apply up to 2.3 kbar uniaxial pressure along the c axis and find that the high-field phase boundary tracks the upper critical field H-c2. We also report the behavior of H-c2 under uniaxial pressure for field along c.
