| Popis: | Resistivity and magnetisation measurements were carried out on various series of lithium doped YBCO samples in extended oxygen and lithium concentration ranges in which the materials are single phase: 6 x Li −1 per Li + is observed. All the O-samples show superconductivity at H =30 G. The susceptibility data show that lithium gradually destroys either superconductivity (O-samples) or 3D antiferromagnetism (T-samples) and simultaneously localised moments appear since the χ ( T ) magnetic behaviour is Curie–Weiss type. If the observed effective moment is assumed to be induced by lithium, this moment is constant and equal to (1.08±0.11) μ B per Li as long as x |
