UNSPECIFIED. (1994) CU-63 NMR SHIFT AND RELAXATION BEHAVIOR IN TL2BA2CA2CU3O10-DELTA (T(C)=125-K). PHYSICA C, 226 (1-2). pp. 106-112. ISSN 0921-4534Full text not available from this repository.
Extensive Cu-63 NMR measurements have been carried out on a magnetically aligned sample of the triple-layered superconductor Tl2Ba2Ca2Cu3O10-delta (T(c) = 125 K). The Cu-63 shifts in the three Cu-O layers all have a similar temperature dependence to that of O-17, showing that they probe the same static spin susceptibility. The magnetic properties of this material were found to resemble those of underdoped YBa2Cu3O7-delta. The Knight shift decreases dramatically with decreasing temperature below 150 K in the normal state, whereas the nuclear spin lattice relaxation rate (1/T1T) shows a broad maximum at approximately 165 K, indicating an opening of a spin pp well above T(c).
