New data and analysis show that the Hall conductivity O'xy of cuprate superconductors consists of two additive contributions: a quasiparticle excitation term and a vortex motion term. Competition between the two leads to a sign reversal in YBCO but not in LSCO, where they both have the same sign.

We propose a view of the cuprate superconductors based on strong covalent bonding within the CuO2 planes. This covalent picture was developed from an alternative analysis of some recently reported spectroscopic and transport properties of several high temperature superconductors. In this view, antif
The magnetoresistance was measured for both Hllc-axis and HIc-axis, using c-axis oriented films with ~20.6 of the Y, \_,Pr,Ba&u,O, system. The sheet resistance for the CuO, layer of the sample with X= 0.6 is in agreement with h/4e2= 6400 Q/II which is the threshold value of a superconducting-insulat
