Spin Gaps and Bilayer Coupling in YBa2Cu3O7−δ and YBa2Cu4O8
We investigate the relevance to the physics of underdoped YBa2Cu3O6+x and YBa2Cu4O8 of the quantum critical point which occurs in a model of two antiferromagnetically coupled planes of antiferromagnetically correlated spins. We use a Schwinger boson mean field theory and a scaling analysis to obtain the phase diagram of the model and the temperature and frequency dependence of various susceptib...
متن کاملSpin–orbit coupling in a graphene bilayer and in graphite
The intrinsic spin–orbit interactions in bilayer graphene and in graphite are studied, using a tight binding model and an intra-atomic E LE S coupling. The spin–orbit interactions in bilayer graphene and graphite are larger, by about one order of magnitude, than the interactions in single-layer graphene, due to the mixing of π and σ bands by interlayer hopping. Their values are in the range 0.1...
متن کاملQuantum Spin Systems: From Spin Gaps to Pseudo Gaps
Many low dimensional spin systems with a dimerized or ladder-like antiferromagnetic exchange coupling have a gapped excitation spectrum with magnetic bound states within the spin gap. For spin ladders with an even number of legs the existence of spin gaps and within the t-J model a tendency toward superconductivity with d-wave symmetry is predicted. In the following we will characterize the spi...
متن کاملSpin-spin correlation lengths of bilayer antiferromagnets
– The spin-spin correlation length and the static structure factor for bilayer antiferromagnets, such as YBa2Cu3O6, are calculated using field theoretical and numerical methods. It is shown that these quantities can be directly measured in neutron scattering experiments using energy integrated two-axis scan despite the strong intensity modulation perpendicular to the layers. Our calculations sh...
