NQR study of hysteresis in YBa2Cu3O7-x
Bondar' A. V., Ryabchenko S. M., Fedotov Yu. V.
Experiments reveal that the effect of the pinned magnetic flux on the transverse relaxation time T2 of the NQR of copper nuclei in the planes [ Cu (2) ] of the YBa2Cu307 _ x crystal structure is different from that for the chains [ Cu (1) ]. Possible reasons for this effect are discussed.
