Changes of Fermi Surface Topology due to the Rhombohedral Distortion in SnTe
Christopher D. O'Neill, Oliver J. Clark, Harry D. J. Keen +7
Stoichiometric SnTe is theoretically a small gap semiconductor that undergoes a ferroelectric distortion on cooling. In reality however, crystals are always non-stoichiometric and…
Evidence for even parity unconventional superconductivity in SrRuO
Aaron Chronister, Andrej Pustogow, Naoki Kikugawa +6
Unambiguous identification of the superconducting order parameter symmetry of SrRuO has remained elusive for more than a quarter century. While a chiral -wave ground sta…
Split superconducting and time-reversal symmetry-breaking transitions, and magnetic order in SrRuO under uniaxial stress
Vadim Grinenko, Shreenanda Ghosh, Rajib Sarkar +17
Among unconventional superconductors, SrRuO has become a benchmark for experimentation and theoretical analysis because its normal-state electronic structure is known with…
Thermodynamic Evidence for a Two-Component Superconducting Order Parameter in SrRuO
Sayak Ghosh, Arkady Shekhter, F. Jerzembeck +6
SrRuO has stood as the leading candidate for a spin-triplet superconductor for 26 years. Recent NMR experiments have cast doubt on this candidacy, however, and it is diffic…
Electronically driven spin-reorientation transition of the correlated polar metal CaRuO
I. Marković, M. D. Watson, O. J. Clark +11
Polar distortions in solids give rise to the well-known functionality of switchable macroscopic polarisation in ferroelectrics and, when combined with strong spin-orbit coupling, c…
