Shifts of the nuclear resonance in the vortex lattice in YBa${}_2$Cu${}_3$O${}_7$

Abstract

The NMR and NQR spectra of ${}^{63}$Cu in the CuO${}_2$ plane of YBa${}_2$Cu${}_3$O${}_7$ in the superconducting state are discussed in terms of the phenomenological theory of Ginzburg-Landau type extended to lower temperatures. We show that the observed spectra, Kumagai {\em et al.}, PRB {\bf 63}, 144502 (2001), can be explained by a standard theory of the Bernoulli potential with the charge transfer between CuO${}_2$ planes and CuO chains assumed.
