Spin dynamics in hole-doped two-dimensional S=1/2 Heisenberg antiferromagnets: ^{63}Cu NQR relaxation in La_{2-x}Sr_xCuO_4 for $x\le 0.04$

P. Carretta, F. Tedoldi, A. Rigamonti +4

The effects on the correlated Cu^{2+} S = 1/2 spin dynamics in the paramagnetic phase of La_{2-x}Sr_xCuO_4 (for $x\lesssim 0.04$) due to the injection of holes are studied by mean…
