Quantum Antiferromagnet

The normal state in-plane resistivity ρab and the out-of-plane resistivity ρc of high T c cupreous oxides are studied in terms of the interactions between the charged carries and the excitations including phonons in a doped quantum antiferromagnet which can be described by either a resonant valence bond (RVB) state or a quantum Néel state. We found that only in a properly doped quantum Néel state and when the renormalized the speed of spin wave becomes soft, ρab and σc = 1/ρc could have the desired experimental behaviors and depend linearly on T from T c up to room temperature if the quantum Néel state still, persists in high T c samples.

Shed Light

We calculate the influence of transverse fluctuations on the longitudinal dynamics in the striped phase of cuprates by using the bosonization technique. We find that a charge density wave instability can arise if the stripe is quarter filled and the underlying lattice potential has a zig-zag symmetry. Our results shed light on the as yet not understood connection between the formation of a low temperature tetragonal phase and the subsequent appearance of charge order in high-Tc cuprates.

ABSTRACTWe have been investigating the possibility that the presence or absence of hydrogen may influence the electrical properties of the high TQ superconductor YBa2Cu3O7−x. Samples were prepared sintering in wet and dry oxygen, ana have been loaded by exposure to a plasma discharge of hydrogen gas. The hydrogen concentration near the surface was monitored by the H(15N, αγ) C reaction, and the four point method was used for the electrical measurements. The tentative results are that hydrogen content has little effect on either the transition temperature or the sharpness of the transition, although higher concentration may increase the normal state resistivity.
