Part of the NATO ASI Series book series (NSSB, volume 246)


We report on the 205T1 NMR (nuclear magnetic resonance) spectra of one-, two-, three-layer T1 containing compounds below and above the superconducting transition temperature Tc. Two different T1 nuclei were observed, namely those of the T10 layers (dominant line) and a T1 defect replacing Ca in the two- and three-layer compounds. Knight shifts, chemical shifts, Korringa type relaxation as well as highly correlated Cu spin dynamics was separately observed in the same compound.
