Abstract
The temperature dependence and the anisotropy of the Knight shift and the spin-lattice relaxation time (T-1) at the Cu and the O sites of th e full over-doped T1(2)Ba(2)CuO(y)(T-c = O K: T12201L) were measured. The Knight shift values at the Cu and the O sites in the CuO2 plane ar e larger in T12201L compared to those in T1(2)Ba(2)CuO(y)(T-c = 85 K: T12201M). This indicates the increase of the spin part of the Knight s hift due to the over-doping. Based on the comparison between the T-1 i n T12201L and T12201M, the enhancement of the antiferromagnetic correl ation still remains in the whole over-doped region.
