Talk title: Possible order parameter symmetry in the
Noncentrosymmetric superconductor
LI2Pt3B The nature of the order parameter symmetry in the noncentrosymmetric
superconducting compound LI2Pt3B seems to be an interesting and long lasting
problem as findings of some experiments contradict others. The most nearest in
nature of this compound is Li2Pd3B, which shows s-wave kind of behavior and
this is widely accepted and verified. On the other hand the nature of the order
parameter in the Pt compound is still full of contradiction. Based on a spin
fluctuation mechanism we describe the possible nature and symmetry of the order
parameter in this compound which also follow experimental findings. This work
predicts some s(+-)type of order parameter with line nodes as the possible
candidate. More accurate experiments are needed to verify these predictions. Click to download: Presentation File |
