Intertwined Orders in CeCoIn<sub>5</sub>: Neodymium Doping Study

ORAL

Abstract

We measures thermal conductivity measurements on Ce0.95Nd0.05CoIn5 with magnetic field rotating in the a-b plane of this tetragonal compound. The step in thermal conductivity when field is rotated through antinodal [100] direction of superconducting d-wave order parameter with the high field low temperature (HFLT) phase demonstrates robustness of the triply intertwined orders (of pure CeCoIn5) against 5% Nd doping. The hysteresis in the data as a function of field magnitude reveal signatures of a p-wave pair density wave (PDW) in the low field SDW phase as well. Given different origins and properties of the SDW and HFLT states, the presence of three intertwined orders in both phases emphasizes that the presence of p-wave PDW is ubiquitous in the company of coupled superconducting d-wave and magnetic SDW orders, suggesting the general nature of this phenomenon.
