We present an exact diagonalization study of bilayer clusters of the t-J model. Our results indicate a crossover between two markedly different regimes which occurs when the ratio J(perpendicular to)/J between interlayer and intralayer exchange constants increases: for small J(perpendicular to)/J the data suggest the development of three-dimensional antiferromagnetic correlations without appreciable degradation of the intralayer spin order and the d(x2-y2) hole pairs within the planes persist…

The ground state and the phase transitions of the bilayered spin-S anti-ferromagnetic Heisenberg model were studied by Ng et al.1 by using the Schwinger boson mean field theory. In this paper, an

We present a63Cu NMR study of HgBa2Ca2Cu3O8+δ underdoped single crystals with Tc ≃ 115 K. While the uniform spin susceptibility decreases below To ≃ 370 K, relaxation rate measurements demonstrate
