Özet
OpenAlex · lv
We have extended a weak-coupling theory of antiferromagnetic fluctuations to the superconducting state and analyzed NMR data for ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$. Within this framework we find that while an s-wave gap structure with 2\ensuremath{\Delta}(0)/${\mathit{kT}}_{\mathit{c}}$=4 can fit the Knight-shift data for Cu(2) and O(2,3), it does not provide a satisfactory fit to the ${\mathit{T}}_{1}^{\mathrm{\ensuremath{-}}1}$ data. Using a ${\mathit{d}}_{\mathit{x}}^{2}$-${\mathit{y}}^{2}$-wave gap with 2\ensuremath{\Delta}(0)/${\mathit{kT}}_{\mathit{c}}$ of order 6 to 8 provides a reasonable fit to both the Knight-shift and ${\mathit{T}}_{1}^{\mathrm{\ensuremath{-}}1}$ data.
