The magnetic structure of tetragonal insulating YBa2Cu3-xLixOy has been studied as a function of x and y. The Neel temperature and the mean ordered magnetic moment on the Cu2 sites were determined by neutron powder diffraction measurements. The decre

The magnetic structure of two well characterised YBa 2 Cu 3− x Li x O y samples, with similar Li concentrations, x =0.08–0.09, and slightly different oxygen concentrations, y =6.06 and y =6.18, has been studied by neutron powder diffraction measu

The structure of orthorhombic and tetragonal samples of lithium (Li)-doped YBa 2 Cu 3 O y has been determined by neutron powder diffraction measurements. The experiment shows that when the samples are synthesized in oxygen, Li substitutes for the cop

The magnetic susceptibility of various YBa 2 Cu 3− x Li x O 6+ ϵ samples with 0 x c -axis is observed. As the lithium concentration increases, one observes the disappearance of the three-dimensional (3D) antiferromagnetism in favour of a paramagne
